Urbannen said:Xavim is right - it doesn't make a lick of sense. Sorcerers can cast a spell without ever having learned it from anywhere. It's like one day waking up and being able to speak Lithuanian.
Well, duh! It's magic!
Sorry for the sarcastic tone, there, but the point is valid. We are talking about magic - energies that behave unlike anything seen in the mundane world. They don't have to make sense in a mundane fasion.
Waking up able to speak Lithuanian? In the real world, of course that doesnt' happen. In a world with magic, however, there's any number of ways to do that. Maybe some stray magical energy imprinted the knowledge in your brain. Or maybe you have a mystic connection to a "universal unconscous" or a race memory in which teh knowledge is stored.
Simply put - when you are talking about magic, you don't need to be able to explain things in mundane terms. Where'd he get the knowledge? Magic!
