Listen

Listen or "Captain Turtleneck"  is a Fomor Servitor and the messenger of Lord Omogh of the Fomor. He is first mentioned in Ghost Story.

Description
Listen is sent as a messenger to the Grey Ghost, who he addresses as "Lady Shade", from Lord Omogh. He was also the leader of the gang of Fomor Servitors that attacked Molly Carpenter.

Appearance
He wore a black turtleneck, like all Servitors did,

His eyes had changed from a clear grey during the combat with Molly Carpenter—to a deep, deep purple like a "bruised corpse" during visit with the Grey Ghost.

Abilities
Captain Turtleneck is able to remain cool and observant in the midst of combat. He figured out molly's illusions and was smart enough to wait out Harry's fire spell until he wore out.

Weapons

 * Seashell Bombs: tiny nuclear-like blasts.
 * Weapons Belt: gun by his left hand and a short Japanese gun by his right hand, possible a Wakazashi or an ninga-to.

In the Series
In Ghost Story, he led a group that attacked Molly Carpenter as part of Lea's test of her new combat skills.

Listen is the emissary sent by to check on the Grey Ghost's progress in acquiring a body. Lady Shade sent a message back through him that she is confident she will acquire the body and be ready to move against the Ragged Lady and her her allies and to enter the fortress the next evening. It was observing this interchange that Harry realized that he was really dealing with Corpsetaker.
