Fly up to the very top platform of the tower and kill Slagnaros. Make sure to loot the quest item off of the body (The Heart of the Timeforge) because if you miss it you will be waiting a very long time for respawn. The respawn timer is about a 7-8 minutes from last kill.

/way 52.38, 82.91 Slagnaros

[River Song voice] Spoilers!

The whole forge gives off a TARDIS vibe, and the description of the quest item; The Heart of the Timeforge seems to back this up: "Within its temporal shell lies a radiant spark born from time itself."

...but the icon of the item looks familiar... could that- ...is that a Flux Capacitor?
