Lion of Narnia (5)
I believe the answer is:
aslan
'lion of narnia' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aslan that I've seen before include "Lion in the Chronicles of Narnia" , "Lewis's character" , "Noble lion" , "Narnia's "Great Lion"" , "Saviour figure" .)
