Small ruler from Borneo (6)

I believe the answer is:

oberon

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

'small ruler' is the definition.
'oberon' can be an answer for 'ruler' (I've seen this before). I am unsure of the 'small' bit.

'from borneo' is the wordplay.
'from' indicates an anagram (the anagram comes from the same letters).
'borneo' anagrammed gives 'OBERON'.

Can you help me to learn more?

(Other definitions for oberon that I've seen before include "Play King" , "MND fairy king" , "Titania's husband" , "Fairy king (AMND)" , "Titania's consort" .)

I've seen this clue in The Globe and Mail.
