SOE? If you said "Yes!" on both counts, then Vanguard invites you to party it up with the Festival of Gloriann. The major cities have been dressed up in their wintry finest, and gifts have been sprinkled around for all to find.
If you really want to get into the festival, you can learn more about Atnas Claws, meet Randolf the flying reindeer (and perhaps get a lift), and beat up on freaky-looking snowmen. Any similarities to real-world copyrights is just a coincidence. There are also special housing decorations and fun costumes to enjoy.
The Festival of Gloriann is currently lighting up Vanguard, so check it out and give Atnas a high-five for us!
