Shadow Step

Shadow step is a pair of black, silk like boots. In all respects these boots function at there base as boots of elven kind, giving a +5 bonus to move silently checks. There creation however, is not from elven hands, but from the meshing of the bearer who once held onto them.
Zui Shadowstep was an Uldrek rogue from what most sources say. She was not only a rogue however, but an arcanist of some note as well. She loved utilzing illusions and her own skill to confound and bewilder her opponents as she stole there treasures. Zui however was not content with stealing, she was also scholarly, as her training dictated, and so explored the realms of illusions and shadow magic to better help her persona. Zui after all, was the god of black cats. Shadow magic seemed a natural fit. Zui stole and bartered for something called esper silk, a rare film that fell from destroyed shadows and similar creatures. Using illusions she had the film made into a pair of boots she dubbed shadow step. With her new trinkets bolstering her power, and her mastery over black cats, Zui became the premiere thief around Uldrek. This unfortunately got the attention of the cities governors, which demanded that the Samurai take care of the problem. The samurai came up with a plan, to lure the thief out with the promise of a great stone known as the shadow gem, a gem from the very heart of the plane of shadows. Like they expected, Zui could not resist, and under the nose of the samurai, stole the gem. Zui unfortunately did not research the gem as she should have, being prideful of her own skills. The gemstone itself was an artifact of Skisk, and promised to turn any illusions real, and any reality into illusion. For a while Zui was beside herself, she utilized her skills and magics to create vast wealth and haven for her and her cat allies, but it was all for not. Soon she realized that she herself was becoming nothing more than a thing of shadow stuff and illusions. Knowing her fate, Zui set up one last trick. Walking straight into the heart of the samurai clans stronghold Zui came bearing the Shadow Gem. The samurai moved to cut her down, but found that she wasnt real, there swords moving through her without any effect. Finally, her body flickering in and out of existence, Zui had went as far as she could, just outside of the Clan Masters house, and set the stone before her. With a wave of her hand she created one final illusion, an illusion that stretched over the course of the clans compound. The illusion was of fire, rocks, and ruin throughout the compound. The clan leader came out, looked at Zui, the Shadow Stone, and waited. With barely more than a whisper Zui said. "The Shadow Stone is destroyed, what you see before you is an illusion, as is the fire. I have the remnatnts of the stones power, and can turn both to reality, or let them both fade away as I do."  The clan leader gave her a grim look. "Let the stone, and the flames become reality" Zui knew this was the only choice he could make. The stone itself was entrusted to the clan, utilizing it as bait showed how desperate they were to findind a way to sto Zui. It is said that the entire clan, every single member inside, perished that night, and the only remnants were the Shadow Stone, buried under the ash within the compound. Some say that they witnessed no one leave, no one, save a pair of seemingly disembodied boots that walked several feet out of the burning gates of the compound, then ceased moving forever.
