Selium refers to a city in Sacoridia and a school of the same name inside the city. Selium lies to the west of Sacor City. Tuition must be paid in order to attend the school, and as such much of the populous is made up of noble's children. However, the Golden Guardian travels Sacoridia in order to find bright-minded children and bring them to Selium in order to study for free. Karigan G'ladheon attended the school at Selium, but ran away after a fight with Timas Mirwell, which launches her into the midst of the Green Riders.
