Phoenix Spear

Monks carried this decorative spear, said to be made from phoenix feathers, on pilgrimages.

Story
In a country near the border, there was a warrior who did not fear death. His formidable body was so sturdy that even arrows could not seem to pierce him. Because of that, the warrior constantly threw himself in the midst of the battlefield.

Once, a beautiful bird appeared in the warrior's dreams. The bird praised the brave and fierce warrior, and whispered to him that it could fulfill one of two wishes- "end the war and make the world into a peaceful one" or "for him to attain immortality". The warrior chose "immortality".

Ever since then, the warrior in battle became a sight to behold. He cut down enemies like grass, and no matter how many arrows have been shot at him, no matter how many swords he's been showered in, he remained perfectly fine and continued to cut open a path in the enemies. The king bestowed numerous titles and praise upon the warrior, and the warrior thought that his glorious days will continue until the ends of time.

However the war did not end, and the border country eventually came to destruction. The flames of battle expanded and wrought devastation to nearby areas. Trees and grass withered; the people died out, and eventually there was no one who knew of the warrior anymore. No matter how much he starved himself, the warrior could not die. He dreamt of the beautiful bird again. He begged to die, but the bird answered that he couldn't. It told the warrior that he could never die, no matter what.
