The Acorns I believe are held by a dwarf, (can't remember his name)
just past the library but before
the hallway that leads to that very genie,
and also before the room where that thing that is trapped by that crazzzy
machine. The Dryad's are just before Jon Irenicus bedroom and after that room
to the north of where that Oytugh thingie is and the portal.
Good Luck!
