Poggle Huffleprong
Poggle Huffleprong is a boggle (gloom Feykin) resident of Hollow. He was entangled in a scheme by Yira Inkstep, causing him to be turned into a sentient sign warding off visitors from her hut.
In 316 PF, a party of adventurers including Rayla Moonshadow, Dac Earreac, Feyre Blackwood, and Winnow Olafson defeated Yira, freeing Poggle from his fate.
