Brittle Billy

NPC overview

Brittle Billy, brother of Halk, is a fey with living hair and a runed weapon, known for his cleverness in creating constructs rather than traps. He is based in a workshop above the fort’s Southern Tower. He utilized book magic and constructed a skin-covered book that spat wasps from its mouth, which roamed the main hall without obeying him.
During an encounter with the Fangwood Six, he fought from the doorway, tangling Bruneg and Arsène in his hair while using mocking magic to slow Vendel Coldblade. After sustaining wounds from bombs, arrows, and force magic, he surrendered and warned that a gear puzzle box contained spring-loaded green slime. He claimed that the leprechauns had wrongly labeled him a trapmaker, stating he mostly made constructs but struggled to control them.
Brittle Billy is associated with contraptions and mechanics. Fangwood Six fought him earlier but did not kill him; he gave them access to fight Hulk and promised to help set traps. Before the party went upstairs, they asked Brittle Billy what remained above. He said the atomies occupied one side of the fortress, but he had never crossed into Hulk’s section beyond the sealed door.
Following the fall of Halk, he accepted the offer to keep Halk’s club, open the hidden caches, remain in the fort, and build defenses and useful constructs while helping to rebuild its walls.
