From publisher blurb:
The draconic race awoke soon after the universe’s creation-- only primordials and the gods predate them. The greatest, most ancient of wyrms have passed on to the higher planes, but their essences remain, powerful life-energies that can guide and influence other beings who know how to call upon them.
Warlocks forge pacts with the primal dragons, gaining a special connection with one draconic type, but able to call upon others as well. With a simple word a Warlock can blast their enemies with deadly elements, invoke the strength and power of a rampaging dragon, and tap the race’s ancient knowledge.
This pact features a full listing of powers from Levels 1 through 30, four new Feats exclusive to the pact, two paragon paths, and four new magic items.
