What Good-aligned wizarding factions are there?

I play a 10th level neutral good gnome wizard. The majority of my party (barbarian, arcane trickster, warlock, Ranger, and druid) are part of factions in game. I’ve been trying to find a group in the Forgotten Realms to join to learn from.

So far the only real groups I’ve found are the Arcane Brotherhood and the Red Wizards of Thay. The only issue is that both of these groups are evil aligned.

Are there any factions for wizards that aren’t evil? I’ve heard about Silverymoon and Blackstaff, but I can’t find any information associated with those groups.
