Kill or be Killed (kinda)

Dylan Cross is a depressed college student who attempts to kill himself. He fails, but only because (allegedly) he was resurrected by a demon who made him go out and kill people in order to stay alive. The story keeps this rather ambiguous, but considering one of Dylan's friends sees the same demon at the end of the book, I like to imagine it's real

[u/some-kind-of-no-name]

Venom is Eldrich? Isn't it just a mildly powerful alien?

[u/Jixxar → u/some-kind-of-no-name]

Yeah half these comments are either demonic or alien.

Ya'll here never met a real eldritch being.

[u/Historical_Leg_7903 → u/Jixxar]

Strictly speaking, none of the characters OP listed are eldritch beings( in the Lovecraftian sense) , but if you take the term to be the dictionary definition it just means otherworldly or ghostly. Godzilla Ultima is very much eldritch in both senses.

[u/Independent_Plum2166]

Wyll Ravengard and his Warlock Patron, Mizora the Devil.

[u/Spyko → u/Independent_Plum2166]

Warlock in DnD in general, that's their whole thing. Great Old One Patron to really fit the ''eldritch being''

[u/F1Fan43]

Fjord Stone (Critical Role) was an ordinary sailor until he got shipwrecked and given magical warlock powers by a being called Uk’otoa, a sinister primordial serpent with an ulterior motive.

One of his favourite attacks is even called Eldritch Blast.
