As Tyler worked in a secluded corner of the castle grounds, the map had led them to an ideal hidden spot for creating the arrays without being disturbed. While Tyler was focused, Lily, Mana, and Mathilda stood outside on watch duty, scanning the area to make sure no one approached.
Mana, growing bored of standing guard, floated back to Tyler, her curiosity getting the better of her. "What kind of array is this?" she asked, peeking over his shoulder.
Tyler glanced up from his work, patiently explaining, "The array in that building is a combination of an Alarm Array and a Lightning Array. The Alarm Array sends a signal to the main system somewhere in the castle when it detects an intruder. The Lightning Array stuns the trespasser and paralyzes them."
