Maple the Autumn Guardian
"Maple the Autumn Guardian is the ever vigilant sentry, tasked with keeping a close eye on the Twilight portals. To carry out this task, the Autumn Goddess has granted her the ability to see the world that lies in the in-between.
Maple has always been considered more dangerous than the Spring, Summer and Winter watchers and has thus been assigned to the Twilight portals, the thinnest veil that lies between the light and the dark. Maple is able to channel the power of the in-between through her staff, giving her both the offensive magic that lurks in dark and the defensive power that shines in the light.
While patrolling, Maple noticed one of the Twilight portals beginning to shudder violently. Without warning, the portal burst open, sending hundreds of Titans flooding outwards. Maple looked around frantically for help as a large shadow formed where she stood. Above her was a huge, winged beast with green scales and sapphire eyes. Atop the flying beast sat a girl, eyes fixed on the monsters spewing from the portal. Maple was the Autumn Guardian, and it was her job to defend against whatever came through the portals. As Maple charged the growing Titan horde, a loud roar echoed through the sky and the girl and her beast dove into the fight. With their help Maple forced the Titans back through the portal, drawing enough energy from the in-between to seal it once again.
She inspected the portal and noticed large, cracks beginning to form. The portal would need to be repaired to prevent another outbreak of Titans, or anything worse. To thank the beast rider, Maple would allow her to stay among the Guardians and the rest of her company, keeping watch with her until the Portal could be fully repaired."
