Where can I find more information about the Cat Lord?

I’m writing my own D&D universe and there are two deities I’ve chosen from the official setting to incorporate: Lolth and the Cat Lord

The Cat Lord seems to be depicted as a deity for the Tabaxi in Volo’s Guide to Monsters. I’ve tried to find more information about the church of the Cat Lord, how they work, their beliefs etc. but I haven’t found anything.

Where can I find more information about the Cat Lord, especially focusing on mortal worshipers (organization & hierarchy, rituals, worldview, etc.)?

What events are depicted in these frescos from the “Shield of the Hidden Lord” DMsGuild module (which expands on the Descent into Avernus adventure)?

There is an unofficial module on DMsGuild named "Shield of the Hidden Lord" by M.T. Black – who is one of the writers on the official adventure Baldur’s Gate: Descent into Avernus, so I assume its lore is correct.

Pages 7-8 of the "Shield of the Hidden Lord" PDF include the descriptions of 4 frescos on the walls of area T2. These paintings reportedly depict Gargauth (presumably different key aspects or events relating to Gargauth).

What events or aspects exactly are depicted in each of the following frescos?

First Fresco. A handsome sage in amber robes sits on a throne with a pile of scrolls next to him. He is speaking to a group of kings and queens, who listen to him with interest and respect.

  • I suppose this is just an illustration of Gargauth’s charming abilities. Is that the only meaning?

Second Fresco. The sage in amber robes looks at a city in the background. The city is burning, and soldiers fight in its streets. In the foreground are two snakes, twisted together.

  • What city is depicted here?
  • Who are the soldiers, and what organisations do they belong to? Why do they fight?
  • What is the meaning of these snakes?

Third Fresco. The sage in amber robes rides a blue dragon over a dark forest. In a clearing in the forest is a unicorn with a broken, twisted horn.

  • I found this dragon’s name: Rathguul. Is that right?
  • Why is there a unicorn?
  • A twisted horn is Gargauth’s holy symbol. But the module says that Gargauth’s holy symbol is a Knight of the Shield badge. What is right here?

Fourth Fresco. The sage in amber robes wields a rapier and fights a shadowy figure in dark armor. The shadowy figure wears a jeweled gauntlet.

  • Why a rapier?
  • Who is the figure? Bhaal?

What does the attuned creature know about the Shield of the Hidden Lord?

The DMG states that all properties of a magic item are known to the attuned creature, or a creature that spends a short rest analyzing it, but what about the Shield of the Hidden Lord? Some properties of the shield aren’t usable by the attuned creature. Plus, it seems kinda boring to me that the player would instantly be aware of Gargauth’s true nature after an hour of attuning or analyzing. To me that is something to be found out via play or identify.

What happens if a demon lord is redeemed?

According to the description of Scepter of Shibaxet (The weapon of the Kind of the Wind Demons, Pazuzu) a demon lord can be redeemed

The Scepter of Shibaxet can be broken by a redeemed demon lord if the regenerating towers of Shibaxet are already destroyed.

The towers are his rookery, and can be found in his Abyssal plane.

But what happens after a demon lord is redeemed? Do they become gods or do they stay as demons or does something else altogether occur?

Shield of the hidden lord, +2 or +4 to AC?

So, when you attune to the shield of the hidden lord on the adventure “descent into avernus”, the object reads as

While holding this shield, you gain a +2 bonus to AC and resistance to fire damage.

The +2 to AC it is what a normal shield do, so my question is if the shield works as a shield +2 or a normal shield?

What balance considerations should I make if I remove the Corruption and/or Insanity mechanics from Shadow of the Demon Lord?

In Shadow of the Demon Lord, there are mechanics that help portray its dark fantasy world. “Insanity” arises from undergoing stressful situations, whereas “Corruption” accumulates as the the character commits evil or dark acts. Both have tangible effects for the character (a high Corruption character would be impossible to resurrect, for example).

Suppose that a group would enjoy the general underlying gameplay, but not the darkness necessitated by the setting.

If I were to remove Corruption and Insanity from the game, what parts of the system would I have to tailor or remove so that the game remains fair?

What demons are related to the demon lord Dagon?

I’m planning an underwater adventure for D&D 5e that will contain an underwater portal to Dagon’s layer of the Abyss (the 89th layer, called the Shadowsea, apparently). The portal will have demons spilling out of it, but it will be quite small at this point so it should be something the party should be able to stop; hence I want to know what demons would be thematic for being underwater and being associated with Dagon.

D&D 5e doesn’t contain much information about Dagon (most of what I know of demon lords has come from running Out of the Abyss, in which Dagon does not feature, or the Monster Manual and Mordenkainen’s Tome of Foes, neither of which mention Dagon at all as far I as can tell). The only things I know about Dagon come from the Forgotten Realms Wiki page on Dagon, which is not 5e specific and therefore draws on sources I don’t have (I only have 5e materials).

This wiki page mentions:

Dagon was served by aquatic demons, especially wastrilith, […]

But it doesn’t further elaborate on what these other aquatic demons are.

The only appropriate demon I’ve come across so far is the wastrilith, mentioned above, which appears in 5e in Mordenkainen’s Tome of Foes (since it is associated with water, though the book mentions no relation to Dagon specifically, but that Forgotten Realms Wiki link does), but it’s CR is quite high for the party level range I’m planning. There is also the hydroloth from the same book, but that’s a yugoloth, not a demon, and I’d prefer demons where possible.

What demons would thematically follow Dagon?

Ideally of a lower CR than a wastrilith and ideally from 5e where possible, but neither of those are hard constraints. I’ll accept anything from any edition of D&D.

Related, but about Baphomet: What demons are under the dominion of Baphomet?

Unlike that question, I’m only interested in demons specifically (unless the creature has business existing in the Abyss, such as yugoloth; I assume that pretty much only demons would be there).

Vampire/Vampire Spawn vs Vampire Slave of the Vampire Lord

So in d&d 3.5 a Vampire Lord creates vampire slaves rather than vampire spawn. However when a creature has 5+ HD is turned it becomes a vampire not a vampire spawn so does this mean that if a Vampire Lord turns a 5+ HD creature its a normal vampire under the same rules of control or is it also a vampire slave? And on another note, are these vampire slaves stated as regular vampires/vampire spawn when created?

Vermin Lord has Pincer Claws ability in table that is missing in text

Page 74 of The Book of Vile Darkness shows the table for The Vermin Lord and at 8th level the ability “pincer claws” is gained. However, in the accompanying ability descriptions for the class, that ability is conspicuously absent. Does anyone know if any official errata exists that explains this ability? Incidentally, I just give my vermin lord (2)1D6 natural claw attacks that if successful can attempt a grapple as a free action. If there is any errata known of I would appreciate the knowledge, thanks.

What is known about tabaxi language and terminology, particularly the word “tabaxi” and the name of the Cat Lord?

According to this Dragon+ article, the term tabaxi originates with the race of cat people (at least in the Forgotten Realms setting as of D&D 5th edition):

Tabaxi with a capital T is the ancestral name of one of a number of human tribes that traveled east to Faerûn from across the ocean…

…although having both tabaxi and Tabaxi in the canon of the Forgotten Realms is confusing, it makes sense for tabaxi to originate from Maztica. This provides the in-world explanation for the similarity of their names: the human Tabaxi named their tribe after the mysterious cat people of Maztica and Katashaka. Also, establishing them as native to that distant land explains why tabaxi are rare across Faerûn in both the past and present.

But nothing further is explained about the name beyond that. I haven’t found any other information about the name of the race, but I am curious what other information there is, e.g. whether the word “tabaxi” ultimately originates from the cat people, and whether it has any meaning other than “this specific race of cat people”.

Likewise, it seems as if the tabaxi should have their own name for their figure of worship, aside from the plain phrase “Cat Lord” in Common. This answer explains that the first Cat Lord in D&D was named Meerclar, but that pre-dates the creation of the tabaxi and the Fiend Folio doesn’t mention any figure of worship. (and the 2nd edition books seem to indicate that tabaxi religion is largely animistic.) Likewise, it’s mentioned that the corresponding figure in Greyhawk is named Rexfelis, but there don’t seem to be cat people in Greyhawk and the Latinate name seems like a poor fit for the tabaxi.

One might presume that “tabaxi” means something like “cat people”, and that the Cat Lord could have some related name in the tabaxi’s language, but is there any established information about these subjects in any official D&D publications?
