"There are lots and lots of kinds of magic, I'm sure someone has tried to catalogue all of them but it'd be like trying to catalogue all the stars. Wizards are arcane casters, rather than divine casters; their power comes from the magical energy inherent to the world, rather than from gods. Anyone educated enough can learn to be a wizard, so it's the most common kind of magic. Wizards can do - most things, really, arcane magic is very very flexible. Relevant to you there's such a thing as an interplanetary teleport and wizards can learn it, though it requires exceptional power and I don't know that there's anyone in all of Osirion who can do it. Absalom will have someone, if Sothis - Sothis is the capital city of Osirion - doesn't.
There are also sorcerers, who have some access to arcane magic through an inherent ability that requires study to refine, but not to use in the first place. Some sorcerers are part dragon or part angel or part demon and their power comes from that. I think there are more than a hundred kinds of sorcerer catalogued, though. There are also bards, who have powers through music, and druids, who have powers through communion with the natural world or maybe an extremely subtle god who doesn't want to admit to being one. There are people who get magic through pacts with extraplanar entities that aren't powerful enough to be called gods. - I do not recommend doing that, many of them are malicious and the pacts give them a great deal of power over you. There are people who get magical abilities through secret traditions I know no more details of.
My magic tells me that both of you are powerful but not - any more detail than that, I couldn't guess just by looking whether you are one of those things or some other sort of thing."
