Hey,
can you tell me what's this mod about?

The description is criptic.

It adds a large Dark Brotherhood themed cemetery/mausoleum on the hillside just east of Cheydinhal, and is very near to the Listener Lair. You need to be a DB member to gain access of course. Provides some nice back story to the DB Faction. Has underground passageways which lead directly into the Cheydinhal Sanctuary which is nice because it provides a means to get in and out of the Cheydinhal Sanctuary without going through the city gates.

Compatible with Khettienna's Better Dark Brotherhood Sanctuary and most of the other DB related mods i have tried. Has a small conflict with UL Cheydinhal Falls which I have a compatibility patch available for.
