Caldera was one of the traitorous six and was the Emperor's Seventh and Final Sorrow. He took on the form of a huge flaming demon and was fought as the final boss in a hellish realm named after him.
He was the only advisor to be properly named.
- Caldera bears a strong resemblance to Skorne, Gauntlet: Legends and Gauntlet: Dark Legacy fame, and may be confused with him.
- This name also applies to the area in which the heroes fight, as a caldera is the "cooking pot" central area of a volcano.
