Dragon Age: The Gathering Dark
The Lost Keep
The ruins of this keep look like they date back almost a thousand years. The stonework is indistinct and well worn but it is likely human in origin, which would make the keep at least as old as the Glory Age, likely older. Nothing but a shattered first floor appears to have survived the passage of time.
The rage demon that spawned the abomination called Mythallen was bound in the keep basement. It used the basement as its lair and held its elven prisoners there.
Another underground entryway from the keep led to an old abandoned chantry infested by undead. The chapel’s warded-off sanctum held the centuries-old body of a Grey Warden and a demented Shade.
