"Hell."

We're keeping Shiklah's insults PG-rated, because no doubt she would've gotten progressively cruder with Satana. Also, if I recall Arcade's OHOTMU entry correctly, he was a spoiled brat failson who murdered his parents when they cut him off, then got into progressively more elaborate hits. (Marvel probably dropped a ball not capitalizing on him when escape rooms were bigger!) OK, the entry doesn't use the expression 'failson' but you get the point; although my question was, does Arcade have skills? Other than killer level design? Maybe we'll see later. 

Also, some time back we saw the old, Amanda Sefton Magik mini-series, and the various Hells of the Marvel Universe were maybe consolidating after centuries separated. "Better to rule in Hell," Milton said, and there's probably no shortage of ambition down there.
