Arcadia (oWOD)

From the White Wolf Wiki, the most complete White Wolf reference

Arcadia is the original home of the fae. It supposedly lies at the center of the Dreaming, but it has been sealed off since the Sundering. (The gates were 'cracked open' by an influx of Glamour at the Apollo 11 moon landing, allowing the Exile/Return of the sidhe.) Now, according to the more-recently returned noble houses, Arcadia is under siege or has already fallen.
