Custos and Caesa

Overview
Custos and Caesa are the two arm bracers equipped by Rayne Tenebrae. They consist of two bracers which extend into a blade and buckler combo to compliment his attack style and semblance.

Custos
Custos is the left arm bracer, which transforms into a buckler with an approximate diameter of twenty centimenters (about eight inches). When Custos is in non-combat form it is just a thickened metal bracer on Rayne Tenebrae's left arm. It's non-combat reaches from covers the entire wrist, leaving three inches or so of bare skin around the elbow to allow for freedom of movement Custos' activation mechanism is a small gripping bar folded back along the inside of the wrist. Pulling this forward will extend the bar, and allow it to be properly gripped. Once gripped, four plates of metal will unfold and extend to create the shield.

Caesa
Caesa is the right arm bracer, which transforms into blade with a width of aproximately two and a half inches, and a length of eight inches. Caesa's non-combat form is nearly identical to that of Custos. Instead of the bracer folding out into a shield however, the blade extends from the end of the bracer when the gripping bar is pulled and activated.
