Sirian (born under Sirius) humans are the descendants of the Project K9 crew that first landed on Amasis 280,000+ years ago. They are taller than “Solarian” (born under Sol, the sun) humans, standing at 7-8 feet tall. Their skin is mostly tan or darker with black, dark brown or grey hair. Intelligence wise they’re equal or smarter than the average solarian human.
The majority of the population lived in a large city in Gigantis close to Zero Beardrag territory, those that seek knowledge and surrounded by technology like their ancestors choose to live with the Wryvirra on Myalna island and those that like to live in a more primitive lifestyle moved to Majestatis. They are multicultural, retaining the many cultures their ancestors knew and since been passed down. They are also willing to learn and share the cultures of the non human races.

The main city was once under control by a chief named Eirik, who was described as narcissistic and racist towards non human races, specifically targeting the Beardrags, comparing them to dinosaurs believing they have walnut sized brains. His actions ultimately started a war with the Zero Beardrags after the King overheard his racist remarks almost completely wiping out the entire population on Gigantis. Eirik being a self important coward, remained hidden in a shelter throughout the war, not once provided shelter and assistance for the civilians. When the war ended he was eventually caught and publicly executed by the Beardrags.
The remaining humans have since spread out in small groups or moved to Majestatis and Myalna island to live with the people who were unaffected.
