Lesser dragons are those dragons without the ability to cleave realm-space and reach the plane known as the Parthen Gare. Among those that have surfaced on Sapience are Yudhishthira, Geh'Shya, Poraeus, Auma, Blu and his departed mother.
Several of the above mentioned originated from the fallen sun Ethian. With their home destroyed during the Morning Star cataclysm, several dragons found themselves deposited upon Sapience.
