Ada

Ada may be in her 60s, but she shows no sign of stopping as she's traveled across the US on her motorcycle for decades tracking unusual weather phenomena. She has vast knowledge about various sciences, including stuff that seems to be purely theoretical...maybe. She can't skip an opportunity to talk about what she knows, but she never talks about herself for some reason.

She encounters Indra on a particularly weird chase one day and the world is never the same for either of them.
