Goblins of the Death Rune

From publisher blurb:

The deranged Goblins of the Death Rune dwell in the old, flooded gnomish minehold of Glimmerstone. Obsessed with magic, the goblins hunt wizards, sorcerers and warlocks and force their doomed captives to add their knowledge to the tribe’s store of eldritch power. But dark things dwell in Glimmerstone’s flooded depths, and the goblins’ depredations may yet hold the seeds of their own destruction...

This System Neutral Monstrous Delve presents the power-crazed Goblins of the Death Rune tribe, along with a detailed overview of the floodish gnomish mine of Glimmerstone.
