The make-shift compartment that temporarily served as Kleister's workshop had been made specifically for the light faey when he was summoned into the Glass Citadel. When the armory tower had been attacked, Kleister had went on to work on the weapons and other magical items that had been deliberately touched in the tower.
Many scepters, swords, shields, accessories, and other fancy items were neatly placed in cases and stands inside his workshop. Archer specifically got attracted to the scarlet blade that has perched on a wooden desk, its scabbard beside it having a light scratch.
"That is one of my first creations for the faey militia. It is made of lava from the Raging Red Rivers of Mt. Pyra up north." Kleister said with a bit of pride in his tone, "A bit crude, but the blade could slice through metal like it was soft cheese."
