Guild Wars 2

I’ve found 2 consoles with this name in the Thaumanova Reactor (Metrica Province), one called Frigidnautics and one Terrafier. Both of them need a key to activate but I’ve found nothing like that. Is there somebody out there who knows more about that?

It is a part of hidden “Defeat Misplaced Steam orge” event.
First of all you should find Matrix Cube Key somewhere inside power plant, it usually takes around 30 minutes. Then infuse it with different powers: Earth, Fire, Air, Water by interacting with Elemental Charger Designators one of which you’ve found. It is located in different parts of said plant. Earth, Water requires you to do some jumping while Air is covered in something and must be cleaned with Clean-o-Matic rifle which can be found in a bush next to heart inside Earth part. The hardest part is fire which requires you to interact with Golem 5000 if i’m not mistaken ONCE Fire Elemental is dead.
After it is infused, proceed to the central room where console is located, use a key and wait for energy field to go down, make sure to announce before activating a console as field goes up in ~5 seconds.
You’ll jump on a floating platform with a button, by pressing it you’ll spawn Steam Champion. Kill it, loot secret chest and to get out jump inside a portal. It’ll spawn you close to Power plant main enterance.
