Dragon Bloodline Sorcerers can have many origins such as descended from dragons or other unpredictable ways. For areas frequented by Korsic peoples, Dragon Pact sorcerers are actually a time honored tradition that can be reliably gained or trained into.
Many Korsic clans (and some of their Dwarven brethren) have maintained the ceremonies and rituals to initiate qualified candidates into a pact with either a specific dragon or a group of dragons. According to the dragons as legends would have it, this is done to allow the lesser races to join the dragons in their grand plans/prophecies for the future.
Older clans that follow draconic traditions usually lean towards shamanism in their spell casting, summoning and using dragon spirits and powers, while newer traditions favor the sorcery and arcane aspects. There is longstanding rivalry between the two traditions (usually non-hostile) with the elder tradition granted an earned respect from the younger.
The Dragon Pact Tradition has several unique spells, powers, and abilities not normally seen in other dragon style sorcerers.
