Absurdly Sharp Blade: The Cutting Edge. Remember that "many things on this side [of the Veil] are more literal than you might imagine."
Fridge Logic: It is the line between theory and reality, between what is defined and what isn't, between open and locked, perhaps between knowing and not knowing. It seems Lady Death has given the key to the answer to all questions right at the start of the story but no-one is the wiser.
Bigger on the Inside: Morlock's shop. According to Cardinal, "Doors don't have to open to the same place on both sides."
Bilingual Bonus: Sort of. If you know how to read Tarot, then you can see exactly why it is that the fortuneteller in Chapter 5 reacted the way he did.
Deadpan Snarker: Cailyn, mixed with enough Good Old Ways style Fey terminology that she instantly gets on Robin's good side.
Exact Words: Cailyn refuses to surrender Cardinal's Soul Jar until she knows exactly what's going on. Now Cardinal can't take it back from her until the Umbra explain why they're after him... something they seem reluctant to do.
Fantasy Kitchen Sink: "Every myth, every belief, every dream, every nightmare, they all are residents of this side. The Veil separates the Every-Day from the Every-Daydream. If Humanity has dreamt it up, you'll find it lurking around here somewhere."
Genre Savvy: Cailyn. Not only does she pick up on things quick, but she remembers legends and myths told to her by her grandmother that prove quite useful when they start coming true.
Meaningful Name / Overly-Long Name: Cardinal the Finder, Lord and Aspect of the Primary Directions, second son of the Lord Navigator, great-grandson of The Seeker.
Powers That Be: So far two have been introduced - Lady Scarring, Aspect of Natural Healing, and Death herself; a possible third, the Earth Mother, has been mentioned, as has a for-sure fourth, Fate.
And, to be painfully exact, the term "Powers That Be" is used to describe what are apparently the most powerful beings in the comic's setting. There are 9 total, listed in the world description page: Bliss, Suffering, Order, Chaos, Energy, Matter, Life, Death, and Void.
The Grim Reaper: The Reapers fit the trope more than Death herself.
The Morlocks: Or more accurately, Old Man Morlock, who dismisses Cailyn's inquiry about stalking Eloi as "They're not nearly as good eatin' as you'd think." Runs a weapon shop in the Wyrd Bazaar.
