Powerful deity representing peace? (4)

I believe the answer is:

odin

I'm a little stuck... Click here to teach me more about this clue!

'powerful deity' is the definition.
'Odin' can be an answer for 'deity' (Odin is an example). I'm not certain of the 'powerful' bit.

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for odin that I've seen before include "Supreme god of Scandanavian myth" , "I nod to the Norse deity" , "Legendary Scandinavian" , "The supreme Norse god and creator" , "who's worshipped" .)

I've seen this clue in The Independent.
