So if I were to implement a romance subplot in Eternity - I wouldn’t. I’d examine interpersonal relationships from another angle and I wouldn’t confine it to love and romance. Maybe I’d explore it after a “loving” relationship crashed and burned, and one or both was killed in the aftermath enough for them to see if it had really been worth it spending the last few years of their physical existence chained to each other in a dance of human misery and/or a plateau of soul-killing compromise. Or maybe I’d explore a veteran’s love affair with his craft of murder and allowing souls to be freed to travel beyond their bleeding shell, or a Cipher’s obsession with plucking the emotions of deep-rooted souls to try and see what makes people attracted to each other beyond their baser instincts and discovers love... specifically, his love of manipulating others. You could build an entire dungeon and quest where he devotes himself to replicating facsimiles of love, reducer a Higher Love to a baser thing and using NPCs he encounters as puppets for his experimentations, turning something supposedly beautiful into something filthy, mechanical, but surrounded by blank-eyed soul-twisted drones echoing all the hollow Disney-like platitudes and fairy tale existence where everyone lives happily ever after.
