TheBlood Rite is an Illyrian ceremony that is completed when a novice-warrior wants to progress to the status of a true warrior. It happens each year in early spring with hundreds entering the area of conifer forests and ravines around Ramiel Mountain. The novice-warriors have their wings bound and lack weapons, magic, or Siphons. The only supplies they have are the clothes on their back. Novice-warriors from the same camp are split up when they start. They have one week to reach Ramiel, scale its side by hand, and touch the onyx monolith at the top to pass. The area around Ramiel is closed the rest of the year to prevent novices from scouting the area to give themselves an advantage. It is generally considered unacceptable by Illyrians for outside forces to interfere with the Rite.
During this time, novices must survive exposure, the creatures of the mountains, and each other as they race against time. Many Illyrians who enter the rite often kill each other for food, clothes, vengeance, or glory.  Old feuds were played out, new ones born, and scores settled. Indeed, the Blood Rite offered a release for the dangerous tension within the Illyrian community. It was better to settle it in the Rite then risk civil war.
Devlon allowed Rhysand, Azriel, and Cassian to perform the Rite despite their status. Each started the Rite at a different location in the mountains, however, all three managed to find each other and survive together. They were the first to reach the monolith that year.
