The first treasury that Elena targeted was located in a city called Zaro. In the slum district of this city, there was a very dilapidated house. A few beggars came to sleep here at night. It was impossible for anyone to think that this almost broken house actually had a hidden treasury with a lot of gems inside it. But as unbelievable as that sounded, it was actually true.
In this dilapidated house where anyone could enter without any restriction, the pirate leader had hidden a good amount of his loot. There was a hidden door in this broken house that led to an underground chamber and that was the place where the valuables were stored. That hidden door had various powerful runes engraved on it so that no one below the level 400 could sense it and only a person above level 500 could open it. So this place was actually extremely safe.
