(An impressive-looking notice on gold leaf parchment, written in a neat, angular script.)
Bounty of 10,000 gold!
I will pay 10,000 gold coins for a live sahuagin! I will pay 1,000 gold pieces for a recently dead sahuagin in good condition. I need a specimen of this man-like saltwater aquatic creature for my studies.
Bring your specimen to the shore of Lake Kuto and build a fire as a signal. Your specimen will be examined. If it is truly a sahuagin you could end up with 10,000 gold pieces. But beware, I will know any forgeries, and I will punish any attempt at deception.
So, capture a live sahuagin, bring him to Lake Kuto, and walk away a rich man!
Signed,
Yarash the Archmage
(Stamped onto the parchment, after the signature, is the image of a silver triangle on a circular black field.)
