The Raven Queen makes her home here rather than the Astral Sea. It also incorporates the Domains of Dread, areas created by the shadows cast by great tragedies in the world. CBR highlighted that "if the Feywild is the Prime Material's dream reflection, the Shadowfell is a mirror of its darkness, drawing from
