I have been working on a custom campaign setting for D&D 5e for a while now, and one of the key themes of the setting is “the races aren’t what you think they are at first glance”.
The drow in particular are not the standard Forgotten Realms drow. They’re nomadic, caravan-forming, heat-averse desert dwellers. They’re charismatic with strong written, musical, and dance traditions. They’re not light-sensitive nor are they evil, but they still use poisons, albeit like modern rat-poison, not sleep poison or paralytic. They engage in peace and trade, have magical affinity, and navigate by the stars.
However, they still revere spiders strongly, and have domesticated some ground-hunting spider species for vermin control and as enormous pets, so a deity whose imagery is based around spiders makes sense for them to have. Furthermore, hunting/war, eternal vigilance, healing and magic, and defending freedom and the weak are the main themes I am working with, considering the roles spiders play in their society as protectors of food stores and wardens against disease; furthermore, they already have deities of the sun (Pelor, covering Life and Light), of trickery and the arts (including weaving and stories) (Olidammara, due to bards being common among them, and covering Trickery), and of the stars (Celestian, covering Knowledge). Rites include insect-offerings and dances while small, unattended shrines are commonplace in their homeland.
So, I ask: how would I make make the lore and imagery communicate to the PCs that this Chaotic Good spider-god is clearly distinct from Lolth, to the point where my players do not jump to the (wrong and quite detrimental) conclusion that these drow are also Lolth-worshippers, with all the Evil-aligned baggage that deity entails, upon seeing spider-themed religious images for the first time? I do wish to communicate this in-character for the sake of immersion, and also as a “backstop” for players who may not pay full attention to out-of-character cues.
