Task: Local (and quite eccentric) poet Iosis Vemarelian wants to write a complex epic using only pens crafted from manticore quills. He wants a healthy collection of quills to see him through this strange project.
Completion: Quills harvested from at least two manticores should be enough to satisfy Iosis.
Reward: In exchange for a delivery of quills, Iosis has promised a payment of a rare book of ancient halfling poetry worth 3,000 gp.
