Well, three times actually, but no one remembers the Lenape name for NYC. However, not all Lenape and Dutch were happy with the transitions of power of the island and the areas around it, and many restless Dutch and Lenape spirits haunt NYC’s locals. Every so often they rise to prominence (the last being the Goser Incident of 1985 (aka The Nerve Gas Attack of 1985 to Norms)) and are put down through various magical and/or technological means.
New York is a city of history, from the British occupation during the American Revolution, to the Gang Wars of the 1800s, to the tragic events of 9/11. And all this history creates powerful spirits, ghosts, and other things that go bump in the night.
Needless to say, there are an abnormally high number of Ghosts present throughout NYC.
