Dragon Age: The Gathering Dark
The Crumbled Tower
An ancient stone watchtower built next to a waterfall, likely dating back to the days of the Tevinter push against the elves.
Blacktail was performing his foul ritual here when the heroes slew him.
Later this is where the Mad Apostate was found by Ser Bridget, Eshara and Ser Blaker and where they faced a Rage Demon summoned by the lunatic, as a sick game. The trio recovered the Tome of Blood but Ser Blaker paid with his life. Eshara deemed it unsafe for the elves to inhabit and informed Orellis about it.
