The rocky ground is uneven and jagged basalt and obsidian dusted with wet black and gray sand. The landscape is pocked with deep crevasses, sinkholes, and caves interspersed with spiny boulders as large as a bear. The ocean sprays up through the lattice of caves, and magma pipes blossom unpredictably in the low spots. The seawater and magma combine to shroud the causeway in a thick mist, sporadically limiting visibility to thirty or forty feet. This war between magma and seawater results in a landscape that is continuously being devoured by the sea and reforged in fire.
