"What? No, the Champions control their Divine Beasts with their minds after they've soul-bounded to them. Where did you get that idea? Sheikah Slates are general-purpose authentication, computation, data storage and mesoscopic energy manipulation devices! The ultimate multitool of the ancient age!"
She finally digs up a notebook and leafs through it.
"There are basic functions like programmable computation, mapping, aetheric telecommunication, instant transposition—the last one's very useful if you're going to be bopping around like Linky is—but there are also runes, the best thing about them! Modules you can swap out to channel the fully generic energy manipulation abilities of the Sheikah Slate! You can have six in total, with my upgraded slate."
She plops the book down in front of him, open to the first page.
"I have an index here of the ones we've recovered or reconstructed, even some I invented myself!"
