The Dead Lands are a vast, barren region of The Underland. They are largely devoid of life, with the only known inhabitants being the gnawers. Two of the five known passages connecting the Underland and the Overland emerge into the Dead Lands.. Ripred and his faction of gnawers reside in the dead lands for a period of time as does Twitchtip. The quest of The Prophecy of Gray cross the Dead Lands as they attempt to rescue Gregor's Father.
Also, in Regalia, any person or flier who betrays his, her, or its bond, will receive banishment to the Dead Lands alone, which results in death, either killed by gnawers there or starving to death
