| ||Eyck is a match for any monster. He's even killed manticores and gryphons. He's dispatched a few dragons, so I've heard. He's good. But he spoils my business, the swine, because he doesn't take any money for it.|| |
|- Geralt to Borch, pg.19 in Sword of Destiny (U.S. edition)|
Eyck went to Hołopole after a summons went out for a dragon-slayer as did many other potential trophy hunters.
When an avalanche hit the band of would-be dragon-slayers, Eyck helped Dandelion save Geralt and Yennefer who nearly went over the edge and were very close to falling to their deaths, not to mention arguing. Once he had saved them, though, he demanded that the king "clear the ranks of the filth", including Geralt and Yennefer.
He challenged Villentretenmerth like the good knight he was and the dragon knocked him off his horse with the most effortless flick of its tail, damaging his spine and legs.
- In The Hexer TV series, he appears in episode 4, Smok.
- In The Witcher (PC), Siegfried of Denesle claims Eyck was his father and had died in a battle with a manticore "despite his infirmity" while Siegfried was away from home. From the engravings left behind by Eyck, Siegfried gleaned his extensive knowledge of the cockatrice.
