The sanctuary is larger, better lit, better furnished you have a few extra amenities that most Skyrim players enjoy having in their homes, like book shelves, artifact displays and crafting stations. The Dark Brotherhood Reborn - Dawnstar Sanctuary SSE(aka Sancturary Reborn - SR as referred to in this description), by aluckymuse, is a mod that changes that.
The rabbit hole you call a sanctuary is hardly a place you'd like to call home. But, once you finish its main questline, almost everybody's gone and you're left with an infinite loop of small radiant quests the family you grew used to is mostly dead and in its place you have a few generic NPCs that can follow you and. The Dark Brotherhood is, arguably, the best developed faction in Skyrim.
