Drelb

A glowing man (also known as the Haunted Custodian and the Glow Man) with an icy touch. Its touch is so cold an disconcerting that those so touched collapse to ground screaming in pain.

Though the Drelb is in appearance, very similar to the Wight it is not undead. It will use this confusion to its advantage. Should it think a cleric is trying to Turn it, it will constrain its glowing in an attempt to make it appear that it is moving away. In fact it is growing closer, its chilly hands at the ready.
