While I was running around on my level 7 Wizard, suddenly, the ground started shaking. I was teleported into a large castle and thrown into some massive fights with several other people. I leveled up twice before we entered Oryx's Chamber.
Unfortunately, once we got to fighting Oryx, I was one-shotted by a Ring Element. After I rerolled and spawned back in the Nexus, I tried asking people in chat whether there was any way to get back into Oryx's chamber if I died during the fight, but no one answered. No one answered me in Realm chat either, and Oryx's article on the official site has a link to "Oryx's Chamber", but there's no page created yet.
Is there any way for me to rejoin the fight against Oryx if I die, or was this a one-time opportunity and I'm stuck waiting until the next cycle?
