So I've heard the phrase "Theran Immortals" somewhere once, and I was wondering if they are really a thing or not. Also, I'm wondering if other immortals might have survived through the low mana times, like vampires or whatever. I assume vampires needed too much mana to survive the 5th world, but I'm in no way sure of that. So, anyone got anything for me? Fine with actual RAW or just speculation.
