The Sanctuary is the place in the city where Elixir is generated.
The higher the level of the Sanctuary, the more ceremonies it can queue and the more Elixir those ceremonies will produce.
Ceremonies are regularly reshuffled, so the ones that were not celebrated will be lost. You can always refresh the current ceremonies immediately and the cycle will start again.
* Total Power amount provided on each level
Hint: enable VIP to be able to use a Free Finish on the ceremonies.
