could the angels on lowaa be considered seraphim? they are pretty vengeful and angry + seraph means serpent-like, so it would fit with them not having any limbs

Aren’t Seraphim usually depicted with three pairs of wings? (Note: I know little about Seraphims). That being said, the Angels kind of look like Dementors from Harry Potter, securing that reference with Eridan- And they generally evoke that serpentine shape that’s kind of important in Homestuck Lore in general. As far as we’ve seen, they’re just Hope Elementals.
