One possible scenario I got going on as to what happened 15 years ago is that Kento was being convinced by an unknown evil entity that was sealed and not to be talked ever again, Calibur found Kento in the nick of time and took whatever evil incantation instead of Kento becoming a villain. And that leading to the girl in Touma and Kento's childhood being swept by the vortex and the former Saber dying to keep Touma safe. Reason I am thinking this for now is that Kento is feeling guilty for Touma's memory loss and stuff. And yeah, Calibur must be either his dad, brother, teacher, or at the least some parental figure that looked after him.
