Blood Crystal

"The wearer of these crystals will be able to take on the form of whoever's blood they touch."

- Cylferth

Blood Crystals are crystals that have been enchanted to allow their wearers to take the appearance of anyone whose blood they touch.

History
Dagr and Ebor acquired two Blood Crystals from the sorcerer Cylferth, who also forged their Stulorne Blades. They used the crystals to disguise themselves as Sir Oswald and Sir Ethan so they could enter the Camelot Mêlée, where they attempted to kill Arthur Pendragon.

Merlin discovered the crystals while searching Oswald and Ethan's chambers for their Stulorne Blades. Later, after Dagr and Ebor were killed during the Mêlée, Gaius removed the crystals from their bodies and revealed their true identities (Gwaine).
