Astraeus Churchill is a college student in an unknown university who joined the subversive organization known as the Laniakea. The two leaders of the organization equipped him with a special spear that launched splitting shrapnel at targets.
His Above and Beyond counterpart is Aurelia Churchill.
At some point in 2018, Astraeus Churchill enrolled in Philippine Science High School's Main Campus.
Asteaeus flunks a quiz, wondering how his friend Miyahelen even passed it, but she tells him that she had some help from a team that would later be known as the Laniakea. This piques his interest, and Astraeus sets out to join it. As a result, the team's two leaders supply him with hints that allow him to easily pass the next few quizzes.
Later on, Tyriann provides him a spear-like weapon that shoots goop that splits into metal shards, which he uses to help the team infiltrate the Physics unit, solidifying his membership. He also helps Antigone, Cameron, Vikram, and Nimrod enter the team, and assists in plundering the Biology unit.
Astraeus attends the batch's Graduation Ball after he graduates high school. During the ball, he loses his memory due to the cataclysmic result of Sachikayla and Tyriann's falling out.
To be added
Astraeus can somewhat be described as overzealous by his peers, considering what lengths he'll go to just to pass his assignments. He is extremely loyal to the Laniakea primarily due to the L.E.N.S.es affecting his mind, though the incident at the Graduation Ball has changed that momentarily.
