Home of Odin and Thor (6)
I believe the answer is:
asgard
'home of odin and thor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for asgard that I've seen before include "Heavenly dwelling of the Norse gods" , "Famous Irish yacht from the old Norse heaven" , "heavenly dwelling-place" , "land fit for heroes" , "mythological region" .)
