Dragon Age: The Gathering Dark
The Elven Ruin
The elven ruin is an underground remnant from the age of the Elves. It’s past purpose is unknown but the Eluvian at its core draws animals and corrupts the surroundings. The party fought a Bereskarn, spiders and Undead in the ruins and discovered a passageway leading further down, into the Deep Roads. They sealed it and hid the entrance to the ruins so that nobody else find the dangerous artifact.
