Quartermaster (Nilfgaardian Garrison)

"Are you here to spy or haggle?"

- Quartermaster of the Nifgaardian Garrison's tagline, The Witcher 3: Wild Hunt

The Quartermaster is stationed at the Nilfgaardian garrison in White Orchard, and a human amateur blacksmith. He is specifically located standing downstairs from the main building of the garrison, where captain Peter Saar Gwynleve sits. A quartermaster provides clothing, food, and equipment for the soldiers. Geralt will often find him standing beside an anvil and a grindstone nearby, showing that he is currently working on the soldiers' weapons as he is a blacksmith.

When Geralt first talks to him, he accuses him of spying, showing that he does not trust him. He does so again if Geralt asks about camp morale, and adds that their victory is assured and nothing more. However, this may only be a warning since he is keen to trade and do blacksmith work.

Sells
He sells runestones (which were not sold until after the prologue and Geralt comes back) and diagrams:

a few weapons and diagrams (If Geralt sells weapons to him, they will be added to his arsenal) — mostly steel swords:
 * Velen longsword
 * Koviri cutlass
 * Rusty Velen sword
 * sometimes a pickaxe and Disglair - a silver sword
 * Diagram: Disglair
 * Diagram: Koviri cutlass
 * Diagram: Velen longsword;
