The Wall (part-1)
Ryan watched intently as Ylerias put up finishing touches on the small piece of the wall he had erected for her to write her runes on top of it.
Ylerias finished she spoke with a huff, "These are the runes that would cause any creature from trying to climb on the wall unable to do so, and on top of that I have placed an array that would act as a shield to withstand in case of any physical and magical attacks up to a certain level."
As Ryan paid undivided attention towards her Ylerias continued, "Any rune generally can be divided into four parts, power, storage, controller, and executor, amongst them the power is self explanatory as it supplies power to the rune cluster, storage stores the instructions, controller is the one that makes that the instructions are followed, executor executes it as dictated by the controller."
Ryan scratched his chin as his face morphed in deep thought as he spoke, "I see, but about the power how do I supply it."
