Role in The Tempest (7)
I believe the answer is:
caliban
'role in the tempest' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for caliban that I've seen before include "Creature in The Tempest" , "Brutish man named in Shakespeare's Tempest" , "brute!" , "Character in The Tempest" , "Monster in "The Tempest"" .)
