Art by Steve Argyle. From the L5R art Tumblr, which writes about this art:
The biggest of the Celestial Swords, embedded with jade, reforged and the Celestial Sword that’s seen the most action. Even the saya is sturdy enough to be used as a weapon. It has one of the longest handles indicating military use over style as well.
This one may end up in the blogs’s masthead one day.
