The "Lair of screams" connects to dozens of modded locations and includes stuff from over 250 mods (spells, armors, npcs, weapons.. etc.) All within the lair.. The sds collection is completely unique in that all the mods in the collection are used by SDS mods to add stuff to the lair or to sds npc's.
No other collection with 600 + mods does this.. Its not just a bunch of mods. They are all tied together. In fact the lair with all addons now connects over 250 cells.. and has spells, weapons, armor, npcs (many fully voiced) from over 250 mods.. this is not just a serana mod.. its an entire world built around her (and its not pretty).
If you get the full collection each hold has mutiple sds properties, sds patrols, vendors, etc.. in all literally thousands of npcs, hundreds of locations, and all centered on you being Serana's savior.. do you accept the title? (all links nsfw)
If you look at my optional files, SDS connects or uses several LL mods to make the experience even better. MME, SGO, Diary of Mine.. It ties it all together. enjoy!
