The Pathfinder Society seeks the ancient ruby ring of the salamander and it falls to a team of Pathfinders to find it. Last seen in the Tri-Towers Yard, a once elite academy for the youth of Absalom, the ruby ring is now lost in the Drownyard, all that remains of Tri-Towers after it was destroyed a decade ago in the great quake. The Pathfinders must risk the strange black ichors and salty brine to find their prize—will they risk their very souls as well?
