The Elder Vampire

Your patron is a powerful vampire, immortal beings that most likely have lived for eons. While most of those creatures rely on lesser vampires and beasts to do their bidding, some of them prefer to work with mortals, granting them some of their power in return for their service. Although striking a pact with an elder vampire can grant incredible physical and magical abilities, one should always be aware that such power always comes at a price.
