The Sacred Place: This is a place that exists as a connection in the EC series. This place has been hidden for a long time and visited by few.
Ester’s Summit: Somewhere in Africa, this is where Ester lives, but more importantly, where she rests and keeps her peace and is able to communicate with angels. Humans are not allowed there and very few half-breeds have been there.
The Holy City: This is a generic place that’s based on many ideas of what holy cities can be. It is most likely located near eastern Africa or the Middle East, simply because that is where many holy cities for monotheistic religions actually exist.
