The Shattered Halls

"Yep, it's one big mess, and I'm the one stuck with it"
-Arcturian 
The Shattered Halls are a cluster of realities located somewhere in the multiverse. Any and all stories written by the Sic'h Il-Dun are located here, in the halls. The founding of the halls dates back to the arrival of the Silence. As sections of the multiverse were consumed all around it, the sic'h il-dun outer gods began to actively manipulate the worlds they originated from in order to stop their extermination. They also began to record the changes they made. Over time, these changes compiled into books, and these books compiled into libraries. 
These libraries are sanctuaries without the influence of the Silence, and can be found in pockets all across the halls. Many of them are occupied by various denizens, and can grow into their own lands and kingdoms if large enough. Resvynx, Pandora's Box, and the many, many pocket realities that straddle worlds like Cosmos.
