City of Churches
The Nevernever and Adelaide
With the two Ley lines meeting and forming a minor Vertex under the city it brings the Nevernever dangerously close to the Mortal Plane and many portals are situated around the city.
But the Fae cannot simply enter and leave the city at will, firstly the placement of the churches has pushed back the barrier and made many portals dangerous or outright deadly for Fae to cross
Secondly the Nevernever around Adelaide is a barren wasteland. Although under Summer’s sphere of influence (thus protection) few Fae dare to tread there – there are dangers from the raw magical energy from the Ley lines and there are deadly beasts that are attracted to areas like these.
