Clow Reed (クローリード) is a fictional character created by CLAMP that appears in Cardcaptor Sakura, xxxHolic, and Tsubasa Reservoir Chronicle. He is known as the greatest magician of all time as he draws his magic from his half-European, half-Chinese heritage. He is the creator of the Clow Cards and their guardians: Cerberus and Yue. Sakura and Touya are Reed's descendants, since their biological father is half of Reed's reincarnation, as is as Syaoran, who is a descendant of the original Clow Reed.
