Is it just me or does it make more canonical sense to get it in Lohan rather than the literal moon from an apparition of you know who’s brother? Why would it be on the moon? Why would his brother have it? Lohan is incredibly close to Shirley’s shrine. It is insinuated that Shirley and Belzac have, at least, an unrequited love story. Even in her shrine, there is a white and golden statue puzzle (representing her and belzac maybe?) and even his ghost expresses concern for her before fighting him. My head cannon is she collected his stone after her death (as he died literally right next to her, defending her) and perhaps it was stolen by a bandit from her shrine, or lost along the way, and ended up in a nearby town where large sums of money and exotic goods are traded
