Grendaju was an icy landmass at the southern extreme of the planet Kalee.
It was believed that Grendaju was the last land where the karabbac were known to roam, and it was thought that Ronderu lij Kummar hailed from this area. Qymaen jai Sheelal was once shipwrecked on Grendaju, during which time he found and recruited one of the khans of his Izvoshra elite.
