Dreamwalkers are humans who are using astral projection to enter other realms via the gyrus. They can access a myriad of worlds.
Every Dreamwalker carries a totem known as a bridge which takes the form of an item considered most sentimental to that person. This bridge is what allows a dreamwalker to return to their body on Earth and thus, it is of utmost importance that a dreamwalker keep their bridge safely guarded. If lost, not only will a dreamwalker lose the ability to return home, but also lose all memories associated with the object the bridge takes the form of.
Dreamwalkers have formed several different societies and cultures over the millennia. The Ahona are one such people group.
