The Core is creating something but what

Madison wakes up to find the Core is changing the mana that was absorbed. It's a deadly process to humans with out the elements that are being changed to one another.

there is pure mana that takes the wishes of the person using it like Madison with a wish to know what's around her the only thing is depending on what the pure magic does to determine the mana used hers was rather simple because everything that Madison knows will be shown. it can take information from other people or spirits but that adds extra mana usage. she usually never goes that far because it uses too much mana

Not to mention she has never been in this kind of scenario where she would need to detect mana so the (mana absorbed ?) is normal and she doesn't use other spells then pure magic and summoned things use different amounts of mana depending on power but no one has summoned another person all accounts of it happening were proven wrong one way or another.

[back to the thing most people would be here for]

"Agh"Madison groaned as she woke again face on the floor she decided not to let the Core absorb all of her mana again she then decided to look around after concluding that she won't live for much longer without water she first looked up at the ceiling and found the "sun" but not? The sky but she's under ground there are clear facts that say she's under ground aka the vines are special deep under ground ones that don't need much air and don't like the suns light even if it was only the very smallest bit of sunshine but it's directly in the light so it's not the sun but she could be mistaken about the vines too or a mutation but there is air too it caused her to faint on the spot.
