Ohh, whatever happened?
The Petralith is an important weapon in the fight against the Balaur.
Until now, we thought that only Jotun could manufacture the Petralith, but our research now shows that this is not the case.
According to research, it wasn't Jotun but rather Nevilim who were responsible for manufacturing Petralith.
But that was only a assumption with no proof up til now.
