The interior of the Telvanni Council Hall entrance in Port Telvannis is entirely black, and cannot be lit by any means (I tried holding a light source and casting light spells, and none of these let me see what was inside of the hall). The only way I was able to navigate the area (and poorly, at that) was via the minimap, however this bug made it impossible to go into the chambers cell that I have read about, or the vaults. I don't know what is wrong, but I want to know how to fix this so that I can do more quests for House Telvanni
