" Cameo's glare became the closest thing to a grin Sabin had seen on her face in centuries. "Ashlyn said the artefacts are guarded by the monster Hydra, and Anya later confirmed it. No one has been guarding the girl."
"Perhaps Hydra used to Gard her," Sabin said. "Danika's had to be around since ancient times, but obviously isn't immortal so has had to be reborn. Maybe reincarnated. Or maybe the ability is passed through her bloodline, which is why, according to the gods, the entire family has be annihilated. Or perhaps Hydra simply lost her. Hell, maybe Reyes is Hydra. You've seen how he is with her. "
