Valhalla VIP (4)
I believe the answer is:
odin
'valhalla vip' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for odin that I've seen before include "God - I nod (anag)" , "Pagan god" , "mythological personage" , "Chief Norse god" , "Mythological Norse deity" .)
