Sharper than a Serpent's Tooth (2007)

From the introduction:

A One-Round d20 LIVING ARCANIS Adventure
Old Coryan Adventure 4, Year 5 (Anima, 1029 I.C.)

A group of Black Talon Ss’ressen have come to Old Coryan. They claim to be here on a peaceful mission, one that will ensure the city’s safety. But are their motives as sincere as they pretend? Besides, what could a bunch of Ss’ressen from the Sulphur Marsh possibly know about the safety of a metropolis in the heart of Coryan?

Note: This adventure is a dungeon crawl, which means that it features a number of difficult combat encounters. There are role-playing opportunities in this adventure, but a party that is entirely ill-suited to the hazards of dungeon-delving will struggle.

This CRAWL is designed for characters of 3rd to 15th level (APLs 3 through 15 plus Glory Tier).

Characters not within this level range may not be played in this scenario.
