Make a story about a squad of Immortals, with eerie memory sequences of the days leading up to biotransference, and the War in Heaven. For example this squad is doing a routine patrol of the Hive city ruins that covers their Tomb world directing a group of Warriors, and the Immortal squad leader looks for awhile at one of the Warriors. He says aloud, "do you remember me?" He does, for that Warrior was his dying wife that he remembers carrying to the biotransference forges, promising her that soon things will be ok. As he was an Immortal he has his personality mostly intact after biotransference but she became a Warrior, so he can't meaningfully interact with her. Still the Immortal tries to get a reaction from his former wife, to see some glimmer of understanding in the Warrior's eyes. Definitely a darker story for a comic but it would be interesting to see more stories of Necrons.
