The planet is filled with arctic tundras that cover the most of the planet, a notably section of tundra was known as Tundor Wastes. Travel in the wastes is quite dangerous however, as it is filled with Y.E.T.I.s and Arctic Leviathans, who would happily devour traveling strangers upon first contact.
Grelbin much like Tabora, is filled with various mineral resources, which include the valuble Raritanium and the rare but generally worthless Moonstones (though some individuals attuned to their powers will often pay large sums of Bolts to obtain them).
