		UnderworkerHunter's Journal Entry	Description: "Feeble servant of the Underworks with a long twistpin and hard shell." Hunter's Note: "With all the refuse collapsing throughout their domain, the worker's stiff shell would be essential if they held any hope to survive." Location: Underworks How many needed: 15
		UnderscrubHunter's Journal Entry	Description: "Drained yet dedicated labourer, wielding a coarse steel brush." Hunter's Note: "They they ever hoped to keep their domain clean... What futility." Location: Underworks How many needed: 20
		UndersweepHunter's Journal Entry	Description: "Uses their steel bristled pin to scrub the soot from vents and pipes." Hunter's Note: "Their sharp cleaning implement is as filthy as the rest of the place. They only layer grime on grime." Location: Underworks How many needed: 10
		UnderpokeHunter's Journal Entry	Description: "Drained worker on the verge of collapse. Consumed by the Haunting, they continue to work far beyond their mortal limits."

		UnderloftHunter's Journal Entry	Description: "Exhausted bug, grown sickly from the smog of the Underworks. The worker's twistpins, once tools of repair, now serve as spun projectiles."
