Sorcerers, unlike wizards or warlocks, get their spell casting ability naturally. Whether it be in your genes, or a catastrophic event, arcane magic has fused with your soul.

One can’t study sorcery as one learns a language, any more than one can learn to live a legendary life. No one chooses sorcery; the power chooses the sorcerer.

Think of sorcerers as being a bit like the ‘chosen one’ archetype you find in a lot of fantasy literature - whether it’s through birth or a chance encounter, they’re special because they were made that way.
