They're all mobsters and scum there to buy slaves and whatnot, that much has been made clear. It's the who's who of the underworld, so there's plenty reason to grenade em up a bit. Well, the state sorcerers are there too I guess, but fuck em.
I liked this chapter. The grenade thing was just the kind of out of the box thinking this needs to not get too stale and tropey. There's hope for it still it seems, but it better do more of this and soon, cause the rankings the last month or so were axe-level bad.
