for rhymes,
the raven by edgar allan poe
.... that was obvious.

Well, big fan of Huginn and Muninn. Also northwestern native american legends about Raven. Like how raven made the world, raven made man because raven was bored and wanted something to play with. Raven stole the sun, moon, and stars from the greedy man and tossed them in the sky. Story of how raven tricked crow into ruining his voice and getting all his food. Then there is some stories about raven and the morgan in celtic myth.

oh yes! forgot to mention the two corbs. The poem about two ravens about to dine on a fallen knight and how no one will care because of things int he knights life.

Oh and you got the note from me about the german gothic medieval group Corvus Corax?

Yea I didn't wanna spam 2 posts and this one or that one get ignore so I was waiting a few days before sharing the band's link. :)
