Ergnach

Ergnach is a close friend of Koinzell, and he is the first of the fourteen Lances to be sacrificed. He cast a spell that creates a gigantic wall separating part of the world from the other, but the spell has an unintentional effect of turning the caster into stone. The wall, called the "Heaven's Lance" is eventually destroyed by Koinzell, after making his final peace with Ergnach. (Source: Übel Blatt Wiki)
