Astral travelers sometimes finding themselves passing through a veil of mists and arriving in the apotheosis of sylvan settings, the realm of Arcadia. In this plane dwell forgotten woodland spirits and pastoral gods and creatures out of myth.
Arcadia is hyper-real; it seems more vibrant and alive than the material plane. Smells and tastes seem directly drawn from the most vivid examples in memory; everything is in technicolor and imbued with a faint glow. The world itself is alive--with potentially communicative spirits in everything. Night and day and shifts of weather are sentimental things, sensitive to the meaning of events or the mood of powerful beings.
Arcadia borders other related realms. The Land of Faerie emerges from it (though this realm also has tunnels linking it to the Lower Planes). There is also the Land of Beasts, where the iconic animal lords dwell, ruled over by King Lion.
Despite it’s ties to age-old fables, the Land of Beasts keeps up with the expectations of modern visitors. Adventures from the City have found there home mirrored there in a city of anthropomorphic animals who frequent nightclubs and drive cars. The Cat Lord can often be found here, in the swankest of night-spots.
Magical practitioners view Arcadia and its neighboring realms as places to salvage materials and items out of myth and legend, and to parley with powers that--though perhaps consciously forgotten--still retain great mythic resonance in Man's unconscious. As with all extraplanar dealings, caution is warranted: These primal beings have agendas of their own.
