You can at any time discover previously unknown heritage from any type of being you encounter, even if this makes no sense or contradicts previously established descriptions of your family tree. You always get their powers without their drawbacks, unless the drawbacks are cool and dramatic. Any visible features of this heritage will appear at narratively appropriate moments and be cute, pretty, beautiful, or striking rather than awkward, weird, gross, or scary. This ability works even if the beings in question cannot reproduce with humans, or at all.
