Situated deep in a valley on Ice lies a small forest. The trees are like trees you'll find on any Prime tundra, except they're completely encased in ice and covered by snow. A dark sky hangs over the valley, but a faint light, like starlight, descends from the skies to illuminate the forest. The entire place glows like a magical, crystalline forest lit up by a full moon.

The CalderaBy Center-of-All Source: Planewalker Forums, October 26, 2004 Within the Plane of Ash lays a vast, dark lake. The lake’s waters, though darkened and chilled by the ash of the plane, are mysteriously pure and good to drink from. The water rests in the basin formed by a large, obsidian caldera. The caldera was once a roiling pocket of magma that burst and erupted like a volcano until the frigid, heat-sucking force of the Ash stole the pocket’s fire. It has since cooled enough to contain a large pool of placid water.

Entrope
With a rending gnashing sound the great beast turns an insectile head towards your party, before diving into the ground beneath your feet. A sudden sound of vaccume and wind rushes past as you stare into the void of another plane, the tail end of the segmented worm writhing in the distance.

Without stopping a Tanzu’s actions any ecosystem would be damaged and eventually completely collapse, which brings this odd species of outsider in firm conflict with many a Druid on the Prime.

(Town)Character: Life on the ice is hard, and the people who’ve got the strength to handle it are in charge. As for the rest, endure and keep working, there’s prosperity aplenty, so long as you don’t ask for freedom or happiness and keep your head down when the powerful pass. Don’t trust outsiders, they’re unworthy and can upset and unsteady cart.
