When Krolia and Kolivan revived the Blades and went back to HQ, Krolia found a sketchbook in Keith’s room filled with drawings of Luxite swords.
Krolia recognized each one and knew whose it was before she even looked at the names her son scribbled below every sketch.
As she turned the pages, she realized that they were all swords of Blades who Keith lost on their missions, and she only knows they’re gone because she saw them die in Keith’s memories in the quantum abyss.
Keith honoured his fallen family by etching every single detail of their swords in his memory and drawing each one to never forget.
