Iron
The next day, Kaizen still had to think long and hard about who he would invite to join his guild, and as he had to replenish his store's stock, he spent part of his morning forging.
Kaizen found himself in his cramped forge, a space crammed with tools, materials and unfinished parts. Soft morning sunlight filtered through a small window, illuminating the room, but most of the light came from the heat of the furnace. He was wearing a worn leather apron and sturdy gloves, with an expression of concentration on his face as he held the hammer firmly in his hands.
The iron was glowing in the fire, the flames dancing around it, seeming to obey his will, because he could control them perfectly. With a deft movement, Kaizen removed the metal from the forge, placing it carefully on the anvil. His eyes scrutinized every detail of the piece he was creating, a short sword.
