"Death is the golden key that opens the Palace of Eternity."
-John Milton
Slithering between the Mortal Realms and Otherworld, the liminal plane of Annwn forms the veil and also holds a critical place in the continuation of mortal life. The realm of Annwn is inhabited by the lingering souls of the dead still struggling to unburden themselves of their worldly problems. Those that do, move on to a brighter, more eternal reward. Those that cannot are forced to linger in the dreary little shanty towns that fill the larger caverns of the tunnels snaking their way through Annwn until the besom of Unknown sweeps them away.
