When the iron mines that made Dustpawn so prosperous played out not long after the Goblinblood Wars of Isger ended, the city shifted its focus from mining to goat herding with quite a bit of success. Things have, as a result, been quiet and calm in Dustpawn for the past several years, but that quiet is shattered the night a strange falling star roars across the sky above town to crash somewhere in the hills several miles to the south. When several locals eager to find the fallen star and strip it of its ore go missing, it becomes apparent that whatever has fallen from the sky is much more than a mere meteorite. There are those in town who claim the falling star was in fact a ship, and now a strange malady is creeping through the townsfolk.

Sekarvu is a typical beholder. It spent much of its youth exploring underground realms and killing everything it found. One day, it came upon a large cavern filled with violet fungi. At the edge of the cavern, it found a small band of adventurers who had all but succumbed to the toxins of the fungi's tendrils. They offered little resistance to Sekarvu as it approached and began to feed on their still-writhing bodies. With its first bite, the beholder's life changed forever.

Hidden in the remote southern range of the World’s Edge Mountains lies a mysterious necropolis known in legend as the Tomb of the Iron Medusa.

For the Tomb of the Iron Medusa does not give up its secrets lightly, and the dangerous truths that lie within its ancient, trap-laden crypts may have been hidden for very good reasons indeed.
