Kris, the Blood-Wind

Most aarakocra are creatures of the open sky, bound to the elemental plane of air and the pure, rushing wind. Kris, however, was born under a red moon.

Whether it was because their parents were too panicked to come up with two names, or because they simply couldn't tell the dark-feathered, crimson-eyed hatchlings apart, the name stuck to both. They were the "Kris Twins." Both were dhampirs, possessing the hollow bones and majestic wings of the aarakocra, but cursed with jet-black feathers, a deadly aversion to the blazing sun, and a relentless, shared hunger for blood.

While the rest of the roost feared them, the sisters had an unbreakable bond. They flew together, hunted together, and constantly confused the local populace by answering to the exact same name.
