Skittish when alone, vicious when cornering prey, and unnaturally curious about torchlight, bells, and polished metal. It prefers ambushes from pipes, lintels, and broken masonry, and will circle a fight to attack anyone who looks like a healer or spellcaster.

Gloamdrakes nest in warm sump chambers, fungus gardens, and runoff cisterns where old magic leaches into the stone. They feed on rats, cave fish, and the softer bones of larger kills, but they also lick mineral deposits and rust flakes, as if tasting the history of a place. In Scalewarren Underkeep, the brood seems drawn to the same forgotten vents and sinkholes that the dungeon's other scaled predators use.

A Gloamdrake lair is a maze of steam vents, drain grates, and low crawlspaces lined with half-melted bone and metal scraps. In Scalewarren Underkeep, the lair often connects to the dungeon's older burrows through hidden runoff channels, letting the creature vanish and reappear like a bad rumor.

To defend its brood, hoard gleaming scraps, and expand its territory through the warmest, richest tunnels it can find.

A slain Gloamdrake leaves behind glassy acid-scarred scales, a bile sac worth something to alchemists, and sometimes a half-digested trinket from an earlier victim. In Scalewarren Underkeep, its death often reveals the narrow drain-tunnels and scavenger paths the brood uses to move between lairs.
