Pestilence is tricky, yeah. But death is, definetely, doom. I think, pestilence can be called a union of aspect - a victory of life, that devours another life. Robots are cool, tho. Huh... What about viruses - since Sburb is a game, certain kinds of them can be brought into the game itself... wait. But then, would Maids of Doom be able to create game constructs.

That’s a weird question now, because Game Constructs always seem more Space-leaning than Doom, SBURB is treated as a gate between the Real World and the Session, with the Session as its own physical space- But Homestuck as a whole is also treated like a video game so… I actually don’t even know.
