Aegis

Aegis is a vampire warlock who obtained her power by lying and manipulating a demon to give her the power she desires. She lives in her own secluded palace far from society gaurded by the demon lord she manipulated and his underlings. She is quite the temptress, and she's a liar, narcissist, power hungry, and seductive when she needs to be. Even though she's undead she doesn't serve the lich. [story] recently a mythical book called the book of necronatic lore was opened, unleashing hoards of undead from another relm to purge and destroy this one. This has brought upon a grimdark fate to the world, lead by a powerful sophisticated form of undead... a lich. The lich has been destroying cities with its army of the dead and little hope remains for the living, however, gunpowder is the pinnacle of living technology that can turn the tide of the war. Be whoever or whatever.
