This mod adds a whole new guild to Morrowind, which will have you questing for knowledge and rare artifacts, long lost. You eventually gain the knowledge on how to become a Lich.
World Edits
Adds a number of new locations across Vvardenfell with associated exterior entrances, clutter, and landscape edits. Also adds new quest-related objects and NPCs to a variety of vanilla locations.
Other Notes
Will likely conflict with a number of other mods, though an improved compatibility version is available with support for BCOM, Balmora Outskirts, Rocky West Gash, Secrets of the Crystal City, OAAB - Tombs and Towers, and Ruined Molag Mar.
