Guild Wars 2

Esplen.3940:

Also, the lore of the Thaumanova Reactor isn’t just limited to Asura. Steam creatures in the Shiverpeaks? That’s due in part to the Reactor explosion (and, in other parts, due to the Asura PC with a specific storyline). And in another part of the world, Ascalon has a jumping puzzle that is, in it’s entirety, an extension of the Reactor Fallout. Who knows, we might be fighting creatures from another universe in that fractal if it’s before/as/after the fallout.

Steam creatures are our own creations sent from the future and crystals for reactor were mined in Ascalon, that’s why the area of jumping puzzle is corrupted. It looks like the lore of reactor really is limited only to Asura, unless something drastic happens.

Have it your way.
