Glilandy ís what the devilish Dnyarri called their homeworld. There is very little information about this planet, but it is speculated to have been a very strange and scary world, given that it's intelligent species developed a ghastly skill to control minds.
An Unfortunate lone Ur-Quan explorer discovered this world little over 20,000 years ago and in doing so unleashed an almost unstoppable evil on the galaxy.
It is likely that this world has been destroyed by Ur-Quan, to prevent species like Dnyarri to ever rose from it's surface again.
In The Ur-Quan Masters, the captured Dnyarri pronounces the name of this planet as "Benteflork".
