The Blue Order is an order of wizards who support Saradomin and were one of the founding orders of the First Wizards' Tower. The blue wizards think that Magic should be used to help people. They also created most of the non-combat spells in the Standard spellbook. Known blue wizards are Unaia and Archmage Perien.
After the first Wizards' Tower was destroyed, the Blue Order rebuilt it, and as such, wizards who belong to the current Wizard's tower can mostly all be considered to be part of the Blue Order. Additionally, many may have also joined the Wizards' Guild or the Mage Training Arena, which are also considered to be Saradominist wizards institutions.
