In Underworld Evolution, Selene and Michael travel to seek out Andreas Tanis, who is living in exile.
According to the Underworld wiki, Tanis is spending his exile in a monastery described as a "mountain abode"
For his trouble, he is exiled by Selene, Viktor's personal replacement for Sonja, to an abandoned monastery.
Once a place of worship, this abandoned mountain abode serves a different purpose to the Coven in the late 17th Century. On the orders of Vampire Elder Viktor, it is turned into a place of exile for Vampire Andreas Tanis.
Is there an in-universe explanation on where this monastery is geographically located?
