Heinrich

Heinrich was an apprentice to Archmage Xylem at Xylem's Tower. Only Xylem and his inner circle of apprentices knew the right sequence of activation to enter the tower. Despite this, Heinrich tried to enter, sure that the order was simply right to left. A bolt of arcane energy from the barrier killed him. Now all that's left of him is a pair of smoldering boots.

Speculation
The only Heinrich in the game is Heinrich Stone and they may or may not be the same character.
