Ok fast arcane magic's refluff
Let’s abolish mages. Away with them! All casters are Sorcerers ( if you don’t have sorcerers in your ruleset use mages without prepared spells, don’t make me lose time).
Then, OSR: Magic is Chaos. Now, what is Chaos? Chaos is Entropy, in the form of metaphysic entity. What is Entropy? Oh come on, is Destruction of Information!
So: Sorcerers don’t have spell slots. They have a list of things they have studied before and that they will forget during the day to launch their spells.
Those strange words they utters everytime? It's Common tongue, or at least it was, before Chaos devoured the meaning.
And scrolls that can be used only one time before disappearing? It's the same thing! Chaos feed on the meaning of the words and the spell is cast.
