From the EQ2 Forums:
A new day is dawning in Norrath. Head back to the beginning, gear up and group up, and race with your fellow adventurers! Do you and your friends have what it takes to make it to defeat the final event boss before others on the server? Do so, and you will be handsomely rewarded! (And there are rewards aplenty even if you’re not FIRST!) EverQuest II’s first event server, The Race to Trakanon, is scheduled to open on Tuesday, July 12, 2016.
What are Event Servers? What is the Race to Trakanon Event Server?
Event servers are something new for EverQuest II. Each event server will only be available for a limited time, and it’ll be set in some previous era of EverQuest II content. The Race to Trakanon will be set in Rise of Kunark.
Based on your achievements on an event server, players can earn rewards that can be claimed a character on another server of your choice.
Event Servers require an All Access Membership, and will only be available for a limited time.
