Bas-Lag Wiki

A blitzbaum is a psuedo-tree composed entirely of frozen lightning, held in place by some unknown force. In some areas west of the Cacotopic Stain, blitzbaums occur in large groups which form "magnesium-bright forests" with branching tendrils.

Events of Iron Council[]

During the events of Iron Council, Judah Low passes through a "basalt place" with a forest of blitzbaums during a storm, shortly after leaving the titular train, which has abandoned the Transcontinental Railroad Trust.


  • Blitzbaum derives from two German words, blitz meaning "lightning" and baum meaning "tree".
