- "It dawns on them once they notice my scar: a realization of imminent death."
- - The Iron Wolf
As a condition of the Treaty of Cintra, thirty-two elven commanders that fought under Nilfgaardian banner were captured and surrendered to the Northern Kingdoms, including Isengrim. He managed to escape and fled to the foot of the Elskerdeg Pass, where he met with Sigismund Dijkstra and Boreas Mun, both fugitives for their own reasons. The three of them formed an unlikely travelling party, heading East, towards Zerrikania or even Haakland, presumably leaving the territories of the Nilfgaard Empire and the Northern Kingdoms for good.
- The physical description of Iorveth in the gameThe Witcher 2: Assassins of Kings' journal entry is a direct quote of the physical description of Isengrim Faoiltiarna in the novel Baptism of Fire.
- "Faoiltiarna" is broken Irish for "Wolf Lord", while "Isegrimm" (without the n) is a German poetic word for "Wolf".
