No, those things aren't tied to the original games in any way.
Aylin also confuses me. She should be a half-celestial at the very least if she's actually Selune's daughter; most logically she would be a demigod. She's immortal, which is absolutely not normal for aasimars (I don't even think it's normal for half-celestials). Her power levels are not otherwise very extreme, though. Weird.
