That would be nice but if no unicorns here want to make the excursion I could also just resurrect Tialle for the purpose, I just need to know if this is, in general, an ability unicorns even have.
"Well, that's convenient. Does it have a guess about how they'd feel about it or will we have to find out by asking?"
"Brief period of mutual thought awareness on first bonding. Wears off into background good-at-cooperating after that. Also the bonded can control the dragon's actions but if I'm going to make you omnipotent anyway..."
"It's probably good sense to also ask the dragon but this way we aren't lining up a dozen random people and sussing them out on the subject from zero background knowledge."
"Also before you get a dragon you have to be introduced to sorcery," says Kithabel. "Just lean into my world -" She opens the door again. "And try to feel really entitled about concentrating on wanting, like, that tile to be a different color, or something."
He looks at the tile. He attempts to feel entitled about how it should really be, say, purple.
"Entitled or possessive or indignant or something? You're trying to convince the tile that your opinions about what color it should be are definitely the important thing here and it can just forget about whatever it was doing on its own because you're the boss."
"Right. This is about your mental posture; the tile is just a tile and even the magic ambient to the world isn't actually awake."

If he's going to become the omnipotent ruler of a planet he's going to have to get used to enforcing his will on things sooner or later. That tile needs to change colour because if it doesn't, he can't become omnipotent and take over the world, and it is very important that he become omnipotent and take over the world. So the tile is just going to have to deal, metaphorically speaking, with its new life in a lovely lavender-and-white swirling pattern.
