You want spoilers? Hmm, let’s see. Some characters are human, some are mostly human, some are half human, some are not human at all. Eden/Liv is one of the above. So is Gabriel :) Okay, I’ll give you real answers. But only for Gabriel. Liv is…more complicated. And I’ll make you work for the answer, so I’m not giving spoilers to those who don’t want them.
The elders call Patrick bòcan. It’s Gaelic. Look it up. Patrick says something about his epil in reference to Gabriel. It’s Welsh. Look it up. There you go. You now know something Liv figures out in Visions.
