Xenon

One of the darkest and most feared corners of the galaxy. Xenon has earned the reputation of being the place of no return as proven by the thousands of shipwrecks left by those who try to navigate through the asteroids and perpetual darkness. Asmuth, the creator of the Omnitrix, chose and designed Xenon himself as a way to escape the mayhem of the rest of the Universe to be able to continue his work in peace. He created a device that absorbs all the light in the vicinity, thus creating perpetual darkness around the planet. That, combined with the millions of large asteroids surrounding the planet, ships who attempt to even come close crash blindly onto the asteroids. Asmuth created a homing beacon in the Omnitrix so that if ever it is in range, the Omnitrix will lead the bearer through the dark oblivion to get to its creator.
