Basically,
this mod unlocks both the House of Mania and Dementia upon your
ascension to the Mad God's thrown (IE when you become the Mad God).
The mod will add both keys to your inventory as well as unlock the respective home towns of the Golden Saints and Dark Seducers. All of the appropriate faction ranks will also be granted to the player.
Bug
Fixes: This will also fix the Dark Seducers from the house of Dementia
(kill Syl) quest attacking the player if you picked Mania as your royal
house.
