Guild Wars 2

Haven’t been active lately on the forums and the search function is worthless.

Is there any theory regarding to whom do these ruins belonged?

All of the little knickknacks scattered through the Forts indicate that they were used by the White Mantle before Mordremoth invaded. There are even older ruins scattered throughout the map that were most likely constructed by the Forgotten, based on the hidden cave story chapters.

Nevermind, got my answer through Google.
