Key to Acrylia Carvern

[EZ_Deamel]

ive been hunting in AC and there a room deep in the Zone which i can track some red mob (to lvl 55) but i cant join them. when i click on the floor its tell me something: " You notice something amiss with the floor panels at your feet; however you cannot seen to get them to move." any of you have any idea how i could get to those mobs? its is a key or a quest you need to do to open a portal to move futher in the zone?

i need some info about this if someone know?

Its an event. We tried it several times. Managed to get part way through but never completed it. Its rather tricky and requires at least 24 people maybe more.
