...an other wise useless planet, it is in the same system as that damned cube you're so interested in...
Alkar was formerly a Czerka mining planet. According to thermal scans, the planet once was thought to have a promising supply of plasteel and other metals, but were wrong, as there were few. There was an attempt to also try and tamper with the cube on the other side of the solar system, but again, failed. For the next decade the planet lay undisturbed, until it's star went supernova, destroying the planet instantly.
Aside from the Czerka mining settlement there for three months, there was no trace of anyone who had settled, or even tried to mine the planet.
