* MemeticBadass: Robert Bakker, even after [[spoiler: his death]].
* MoralEventHorizon: To everyone, Bakker crossed the line by killing those against him. For Matthew, [[spoiler:he crossed it when he burnt his own sister and left her crazy]].
* NightmareFuel: Especially given the number of EldritchAbomination types Matthew deals with, there's a lot. The Last Train will swallow you if you don't bring "offerings"; Blackout will [[spoiler:erase the city from the outside in, and once you sleep with it around you can't wake up ever again]]; and the Death of Cities will skin you alive with paper cuts.
