Gallagher, real name Penacony, is a security officer of the Bloodhound Family at Penacony and a slovenly and indolent mixologist. 

Though unorganized in apparel and casual in how he makes his drinks, he is always courteous toward guests but keeps his vigilance about him.

He seems to carry a weight of a complicated past, yet he never voluntarily divulges any details.

He’s later revealed to be closely related to the "Death" that has arrived on Penacony, and a Pathstrider of the Enigmata.
