Yamurlak is a region bounded by Arcsea, and the Buina and Braa rivers which has fallen under various jurisdictions over its history. It is now part of Redania. It was once ruled by Abrad, a secular king known for his anger and cruelty.
- In Danusia Stok's translation of the short story "The Lesser Evil" in The Last Wish collection, she chose the spelling Yamurlak, rather than the original Polish Jamurlak.
- In the German translation of this short story Erik Simon chose Jarmulak instead of the original. But in this case it is also possible that it is simply a misspelling by mistake.
- In The Witcher 3: Wild Hunt there is a spy in Novigrad signing himself Yamurlak who is working for Radovid together with Caleb Menge. Geralt found his letter to Menge and later Triss severely interrogated him about the Dandellion's fate during Count Reuven's Treasure quest. Triss can either kill him or wipe his memory after the interrogation. His ingame NPC name though remains just "Witch Hunters Messenger".
