Ashul Edwaru

The Craftsmaster that created the 13 Month Series. He is also the author of the book "Of the Tower's Weapons". He start the book by explaining that all weapons in the Tower is modeled after the weapons that Zahard and the 10 Great Warriors brought with them when they entered the tower. Thes mean that the weapon design originaly was made for battle in a space filled with air or vacuum, and not one filled with Shinsoo. All weapons therefore had to be redesigned to suit for use in shinsoo.

He end by stating that understanding shinsoo is essential if one wish to understand weapons.
