Temporal Energy Converter

In Dissolution of Eternity the Temporal Energy Converter is a massive device that Quake uses to alter reality and bring about "a new existence of glorious darkness" in a "world of chaos, violence, and pain", as described by the Book of Common Prayer (from the Manual).

Once the Dragon has been defeated, the passage to the Converter will be opened. The device itself can be destroyed directly with the player's weapons, restoring reality back to its intended course (and finishing the game).
