Like, just a sample of what Katja can do:
- Well, they can't kill, whether intentionally or carelessly.
…but they can:
- TF others easily! …which they only ever use in nice, friendly, affirming ways.
- Keep others totally safe. (Hell, if they became macro enough, they could probably keep all life on Earth totally safe from any planetary-scale threat, hypothetically.)
- Generate absolutely wild amounts of power entirely safely!
- Talk™ people out of being awful to others. Like, even the worst person you know. (Through creative application of Not Magic stuff. They can't just persuade literally anyone into not being horrible.)
There's also more neutral silliness going on with them, but, like, the most destructive thing they're willing to do is go swimming in the ocean while macro.
