Yeah, well.
Maybe it's better to give us a historical clue.
Let's do some elimination, then.
Since only two members posted guesses, you could have appointed one of the two.
One of the two posted one answer, but you didn't point him out. Therefore I rule him out.
The other one (me) posted two answers and just one of those is a city.
So it must be Pergamon.
Auris
...fair enough,
here two historical clues;
...something happend there to Mithridates
...the city was devastated by the Huns in ca AD 370
