D&D 4E 4E books with Mystara relevance

[havard]

I'm compiling a list of books in the 4E line containing items (Characters, monsters, places etc) which have a strong resonance on the Mystara lore. For instance, books with references to Orcus or Demogorgon will be included not because they are exclusive to Mystara (they are not), but because of the prominence these entities have in the setting.

D&D 4E Monster Manual 1 (Orcus)
D&D 4E Monster Manual 2 (Demogorgon, Genoids)
D&D 4E Monster Manual 3 (Nagpa)
