I'm replaying the Imperial side of the Skyrim civil war and did the Jagged Crown quest. In that quest Legate Rikke has this line: "But my agents report that Galmar is pretty damned convinced Korvanjund is the tomb of King Borgas. I know Galmar. We fought in many wars together. He's not a sentimental man taken to fancy. If he believes the crown is there... he's likely found it."

So, I'm wondering if anyone knows which wars this would be? I can't seem to find any information on it.
