Arctic region - leader stricken with illness calling me in (9,6)

'arctic' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'region leader stricken with illness calling me in' is the wordplay.
I cannot quite see how this works, but
'region' could be 'island' (island is a kind of region) and 'island' is found in the answer.
'me' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
