I believe the answer is:

wotan

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

'germanic deity' is the definition.
'Wotan' can be an answer for 'deity' (Wotan is an example). I am not certain of the 'germanic' bit.

'transformed a town' is the wordplay.
'transformed' indicates anagramming the letters.
'a'+'town'='atown'
'atown' anagrammed gives 'WOTAN'.

'who' acts as a link.

Can you help me to learn more?

(Other definitions for wotan that I've seen before include "Teutonic god in the Ring Cycle" , "Wagnerian head god" , "Another name for Odin" , "Supreme god" , "Germanic god" .)

I've seen this clue in the Evening Standard.
