The Crooked Man

The Druid Eater
Also known as, The Man in Black, and Walter.

The Crooked Man hunts Druidic energies and consumes them to fuel his machinations at immortality.

He promised the druid Gazer a cure for lycanthropy after he was bitten by a werebear, in exchange for help kidnapping the rats of Big Tree. He seems to have used their bodies for mad experiments, transforming them into Lobstrosities while draining them of their Druidic energy.

As a young woman, Myrtle accidentally tipped The Crooked Man off to the location of her village, resulting in the decimation of her childhood home and beginning her career as a Druid.

He was last seen in the Fey swamps near Big Tree, where the Waterdeep branch of Acquisition's Incorporated drove him off using the protection of one of his true names - Walter. The Tiefling Theris was able to steal his magic hat.
