Greiz

Greiz is an NPC from Act II of Diablo II. He is the leader of the Desert Mercenaries available for hire in Lut Gholein. Greiz and his mercenaries likely helped to defend Lut Gholein from General Malevolyn's attack in the Legacy of Blood, shortly before the Wanderer's arrival. He and his men have been protecting the town from demons ever since the Wanderer passed through, because the city guards were summoned into the Palace to fight off demons erupting from The Palace Cellar.

Greiz and Wirt (from Diablo I) seem to share a common similarity: They both love money, and both have unrequited crushes on barmaids (Greiz's affections being towards Atma, the tavern keeper, and Wirt's on Gillian).
