Where I'm from, a ghost can lose themselves. So hearing him repeat the stories, maybe he doesn't remember anything else anymore.

[ Nico just stands on by while the man fiddles with his omni, watching the door and those runes. He's no expert in Norse, but if one squints, then one of those squiggles kind of looks Norse. ]
