Guild Wars 2

so whats up with these guys, its a group of people mainly a norn mesmer, asura warrior, human necro, and a charr engineer with the medium steampunk armor on.
they’re sitting around in some random place, with a group of 5 hyleks and grawls carrying banners.

you can talk to the main ones and the asura warrior will give you a fight challenge where you have to fight either 5 hyleks or grawls with one being vet. then fight two of the 5 main people, i fought the mesmer and the necro then the challenge was complete and i got a modus supplies chest that acted just like any regular chest.
i didnt get a screenshot of them standing around unfortunately since they disappeared into a portal shortly after.

Seems like a bug in the upcoming Aetherblade update based on Laputa: Castle in the Sky.

You can also find them individually in other zones.

they where sitting in lonars pass when i found them at that spot

There’s one outside the durmand priory who sells you a spoilt potion. Then you beat her up.

but she doesn’t have that guild tag, iv’e met her once before and i never got the chance to beat her up.
but that was way before the dragon bash let alone the aetherblades leak

This is an NPC guild added to the game in October (where they added 30 new events to the game post-launch). The guild has several places in Tyria that it’ll spawn. They’re a fighting guild and they challenge others to fight them so that they can defeat them. It’s just a cool Dynamic Event aspect of the game is all. Cool that you found it.

You buy a potion, drink it, then complain about it not being as advertised.
