tbh sebastian is just coming to watch because burning people at the stake is nostalgic

so yeah please pvp him, he sucks? you can find more info about that here, I say with a sigh

Though despite me being flippant here, it is worth noting that Sebastian will be outwardly taking it very seriously and not showing the fact that he's a shitty demon having a good time lmao... Since he's also a powerhouse, he's very likely to engage any rescuers first to try and allow the burning to go on successfully!
