Erishpamhwen was the third planet in the Wem Dalane system, one position further from the sun than Eniam. Like its neighbor, it had a porous crust with only a small molten core, but its surface was quite different. Eniam was at a good distance from Wem Dalo for life to exist all over the planet, however most of Erishpamhwen was too cold for all but the hardiest of species. At the equator, the planet grew boreal forests where non-native beings could survive.
