The Adventure Zone: Here There be Gerblins
Rimmy_Jim for Yahvvie
Originally known as Yeemik in the Podcast, Yahvvie is a Gerblin that strong-arms our heroes into fighting G'Nash. He is slimy, underhanded, and uses whatever leverage he can to bend people to his will. Unlike the other Gerblins, Yahvvie is quite tactful, and speaks quite calmly.
For Yahvvie, try to think slimeball politician, Lower range on the voice. He's a creature of deception, not outright violence
Apparently Griffin wants him to be voiced by Kelsey Grammer, so here's that voice reference for you!: https://www.youtube.com/watch?v=qDFr_qNO_Vw
(Commanding) HEY ASSHOLES! Put. Your weapons. Down.
(Civil, trying to strike a bargain) I don't think anyone in this room wants to get stabbed any more than we already have, so I've a proposition for you. I will let you leave, alive with Barry Bluejeans here. If you do one teensy-tiny thing for me
(Bone chillingly malicious) I want you to murder my boss.
