(This capital is damn big...) (Lyan)
After summoning his three monsters from the summoning grimoire, Lyan instructed the three of them to get out of the capital and went to the forest in an attempt to level them up and increase their strength. After they travel for about three hours, they finally left the walls of the capital by flying over them.
Even though Lyan keeps on observing the progress of his summoned monsters, he didn't slack on his role as one of the castle guards of the royal castle, and observes the surroundings as well. Along the way, he memorized the layout of the castle and the passages he went, and took a mental note of the sections and parts that are easy to be a hiding spot or a stealth passage inside his mind.
