"Honest!" Temple says merrily. "Okay, the way I give spellcasting to people is casting a spell repeatedly, I will cast it with hand sign language instead of speech to explain spellcasting further. Sorry if the hand signs are disorienting, you don't need to look." With that said he gestures and she understand as clear as day that the completely unfamiliar gestures mean. "Bring Forth Spell-Word." Each hand is casting a different iteration of the spell. "Okay, so the first time I casted this on you it gave you latent spellcasting, which means you can memorize spells from books or use scrolls and spellbooks. A memorized spell can be used only once then you have to memorize it again. Eventually, my spell will give you your own innate spellword, which you can cast as many times you like and it fits you. All innate magic from my original world-cluster fits the person."

All this with explained with a background sensation of "Bring Forth Spell-Word. Bring Forth Spell-Word. Bring Forth Spell-Word. Bring Forth Spell-Word."
