The Clayr are one of the five bloodlines which contain the Charter. Mosrael is in the Clayr's blood. The Clayr live in the Clayr's Glacier, which is north-west of Belisaere and has formed at the source of the River Ratterlin. The Clayr are almost all female, with dark skin, blonde hair and light blue or green eyes. Individually they have the ability to See flashes of the future, but when their Sight is concentrated, as with the Nine Day Watch and other larger gatherings of those with the Sight, they are able to See more clearly and for extended periods of time. The Clayr are currently the largest Charter bloodline, numbering over three thousand (according to Lirael). Because the vast majority are female, they typically reproduce through casual relationships with ordinary men who visit their Glacier.
When the Nine Day Watch first Sees a child (even doing something so mundane as sleeping), the child is permitted to celebrate their Awakening. They wear the clothes of an adult, have a special ceremony and are occasionally called to be a part of the Nine Day Watch. They are now viewed as adults, whatever their age. It is at about this time that they begin their adult jobs (such as serving in the library or the bursar's office) in addition to their Sight training. Most Clayr Awake while they are young, normally around 12. Some Awaken earlier and some much later. Sanar and Ryelle are some of the oldest on record to celebrate their Awakening, their Sight coming at the age of sixteen. It is said amongst the Clayr that the later a Clayr awakens, the more powerful their Sight is likely to be. However, it is possible to be born into the bloodline of the Clayr without having the Sight.
Theory of Male Clayr
(Note that this hasn't been officially confirmed by Garth Nix; rather, it's a fan theory that was posted to Twitter and Garth hit like.)
If the Sight is exclusive to the XX chromosome pairing, then it's probable that male Clayr are XXY, or what are known as Kleinfelter males. That means one in every 3,000 or so births are male, and that male Clayr are generally sterile.
