The last thing Jaskier remembered before being knocked unconscious was the chaos of the raid at Bleobheris—the clash of swords, the whistling of arrows. Amidst the turmoil, someone addressed him as "Your Highness" and dragged him to safety, but not before a poisoned arrow found its mark in his chest.
The arrow didn’t kill him, but it plunged Jaskier into a coma that lasted several months. When he finally awoke, he learned that his survival was thanks to the elven blood running through his veins.
Jaskier discovered that he was the last living descendant of an ancient elven royal line, a bloodline that remained purely elven regardless of human intermingling.
For his protection, the world was led to believe that Jaskier had died during his coma—a loss that Geralt had been silently mourning.
