A Draconic Warlock Subclass for D&D 5th edition designed by Raymond O'Connor.
Good and evil dragon deities play an enormous role in many D&D adventures and settings.
Tiamat, the five-headed god of chromatic dragons, threatens the material plane in Tyranny of Dragons and plots in schemes in Descent into Avernus. Bahamut the lawful good god of metallic dragons stands ever vigilant against her machinations, ready to lend strength to those who would oppose her.
Nicol Bolas plots the demise of the planes in both Ravnica and Theros. Ugin the Spirit Dragon must be returned to defeat him, but which mortal soul will he form a pact with to grant them a chance of resurrecting him in time to face Nicol Bolas?
These are gods in their own right, far more powerful than even the most legendary ancient dragons. Of course, they would entreat the aid of humanity the same way that devils, fey, genies, and Lovecraftian deep sea aberrations would.
