World of Dreams

Also called Tel'aran'rhiod, the World of Dreams is a dreamlike realm parallel to Soyvarhoid. The presence of most creatures in Soyvarhoid is ephemeral here, and they may appear and disappear sporadically, but structures and terrain -- those which have stood still for some time -- have made their mark upon the Dream, and can be found there as well. Some animals are known to inhabit or visit the dream, especially wolves.

Dreamwalkers
Mortals are able to enter Tel'aran'rhiod from their dreams, but this art (usually) takes considerable practice. Those who achieve it are called Dreamwalkers. The Dream is a highly useful state, however, allowing dreamwalkers to explore places they can't reach normally and communicate across vast distances instantly.

There are, however, also great dangers. An unstable dreamwalker might accidentally conjure a nightmare within Tel'aran'rhiod. Moreover, dreamwalkers can injure each other, and often more easily than in reality: Tel'aran'rhiod responds to the willpower of dreamwalkers, so any fate which can be willed into existence can occur. It is also possible for a dreamwalker to examine the ordinary dreams of others as they sleep, and even to enter those dreams -- or perhaps pull those others into Tel'aran'rhiod, rendering them vulnerable.

It is said that some dreamwalkers are able to wake from the dream in a different place than they fell asleep, though there are no known practitioners of this skill.
