Leandre's research notes #DND-001:

"Whilst in our world the art of spellcasting is mostly unknown of and widely regarded as a myth, in various fantasy realms it is much more commonplace. One way to classify these magic users is by looking at where their magic is comming from and by which method they attained it. Case in point, the arcane teachings of the high order of the wizards of the coast suggests the following classifications:
A sorcerer is a magic-user who has an instinctive access to their magic and have most commonly inherited their power from a powerful ancestor somewhere in their boodline, like a dragon. A Warlock has gained their powers through a bargain with some kind of powerful patron, like a demon or fairy-queen. Druids draw their powers from nature itself, while Clerics are able to channel the power of their god into magic spells as a reward for their devoted service to said god. Lastly, a Wizard is someone who has studied the framework of existance and understood how they need to manipulate it in order to calculate their spells.

I wish I could be a wizard sometimes! Math and physics are awesome enough as is, but just imagine you could use them to math up a flame out of nowhere. You could literally calculate your coffee till it's hot! I so wanna be a wizard! But I guess that's not how our world is working. Lizanne and her mentor on the other hand are fortunate enough to be born in some kind of fantasy-realm, wehere magic opperates as described above. We can see Lizanne is currently trying to learn the "Burning Hands" spell, a basic spell that most aspiring wizards pick up early during their training. Speaking of training, I think she might need a little bit more of that..."
