"Of course," Travis replied as he placed the small case within Zuri's grasps.

However before he retracted his right hand, Travis unexpectedly took gentle hold of Zuri's receiving hand and turned it over so the back of it was then showing. His left hand then hovered over and with a brief incantation, a rune slowly materialized into her skin. The process was however painless and hardly anything could be felt from it. 

"Don't worry, its harmless and will fade in time. Think of this as a bit of insurance so to speak," Travis explained before continuing, "Its a recall rune if you must know. In case if things get too dicey or if an opportunity presents itself, I can either quickly bring you back into my vicinity or me to you via my decamp spell which the rune is linked to."

Travis released Zuri's hand so she could expect it though he continued on with his explanation, "The spell process however consumes a lot of mana that I don't have much of, even if I'm drawing mana from one of my crystals. Therefore, we won't have many uses and I am expecting to burn through most if not all my crystals through using other spells. Best we keep on our toes, okay?"
