Breakdown

Keenan's right hand man/woman and another big fan of dungeon life. There is no need to cast a small child for this role - it might even be fun to cast your tallest kid. Cast a performer who is innately interesting and is a strong actor and singer. This is a good role to feature someone who has talent but may not be ready for a larger role just yet. A strange hat or other costume piece might be good for delineating Elf from the other Keepers.
