Lesser dragons are those dragons without the ability to cleave realm-space and reach the plane known as the Parthren Gare. They are more thuggish and bestial than the Greater Dragons. Among those that have surfaced on Sapience are Yudhishthira, Geh'shya, Poraeus, Auma, Blu and his departed parent Ainghaeal.
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.
