Teacher Elider was a teacher at the Institute of Advanced Learning in Gobdor City on Gobdor.
He and his students greatly admired the Earth hero Flash. Hoping to get the speedster to come and talk to his class, Elider sent mental messages to him over the course of a year. Wanting to come earlier but unable due to his busy schedule, the Flash finally found time when things on Earth were going more slowly than normal.
