Yes, the quest does require Amiable faction with Venril Sathir (OT outpost). There are only 2 ways to get to Amiable faction: raise faction via questing, illusions, and faction spell/song; or charm the mob. Here's how I'd break it down:
A. Charm the mob (enchanter, bard, or necromancer)
B. Charm the mob using puppet strings, which go for 10k but are very rare - CT has been dead on arrival for many months on Red, so if you're not in a guild that can contest whatever guild kills it, you can try to buy a charge
C. Faction up by turning in Sarnak braids, etc (pretty doable for evil races or rogues with a Dark Elf mask - 120 braids; no idea how grueling it would be as a non-evil race)
D. Faction up by killing mobs in VP
