Wandering nomad of legendary friendliness (5)

I believe the answer is:

damon

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

'legendary friendliness' is the definition.
The definition suggests a singular noun which matches the answer.

'wandering nomad' is the wordplay.
'wandering' indicates an anagram.
'nomad' with letters rearranged gives 'DAMON'.

'of' is the link.

Can you help me to learn more?

(Other definitions for damon that I've seen before include "Matt --, US actor" , "Pythias's friend" , "Writer Runyon's first name" , "faithful friend" .)

I've seen this clue in the Evening Standard.
