We walked around in circles for a while.
Some drones and helicopters searched above the ground but that was all. They didn't dare to nuke this place a second time which was odd.
Anyway, eventually we made it to the site where Serina was supposed to be. Buildings had collapsed over her.
I had some skeleton squirrels hidden in the rubble and they located Serina's mangled body, crushed between large concrete walls. Apparently the two elves were also nearby, also very dead.
I summoned skeletons within the rubble and made them carry the mangled, somewhat detached pieces underground. Most of the torso was intact in Serina's case but the female elf was in several pieces as was the male elf but maybe not as much. Even if they were alive, no amount of potions or even holy magic could have saved them.
