The Winter Events are a series of holiday quests which run every December.
There are several quest lines varying in difficulty from relatively easy to rather hard. Note that difficulty levels are stated in relation to the other winter event quests. The "easy" quest is easy compared to the difficult quests, but it will still pose a significant challenge for newer players or players with low stats/gear.

Each seasonal quest has numerous rewards, which are displayed year round. To access the reward displays, go to Excelsior Halls and then follow the North path until it curves east. The rewards gates are in the small plaster building.
Note: The rewards displays are updated every year before the quest opens. Any rewards which are different from year to year will only display the current year's version. Past versions are not shown.
Vendor Stones & Quest Currency
Each quest's vendor stone is available only while the quest is running.
You will earn currency items for each quest. The amount you earn is based on the difficulty of the quest, the repeat delay timer, and the items available for purchase.
All seasonal currency is temporary and decays after the quest close date. They will decay at 00:00 shard time on their decay date, which is usually a few days after the quest closes, to account for quest extensions. Note that the vendor stones will become unavailable when the quest closes. You will need to spend your currency on/before the final day of the quest or you will not be able to spend it.
Each seasonal quest has a corresponding totem which can be equipped for a few months out of each year.

All seasonal quests require the most recent Expatch in order to participate.
Pets & Spells
Most seasonal quests disallow the use of pets as well as various AOE spells.
Rule Violations & Event Bans
If you are disrespectful toward the staff or otherwise violate the rules excessively, you may be given an event ban. This means you cannot participate in any seasonal quests or staff-run events until the ban expires.
If you receive jail tasks totaling 10 or higher for ANY infraction while a seasonal quest is running, you will be barred from that event.
If you are found to be in violation of the AFK rules of the shard while inside a seasonal event space, you will lose event privileges for at least 2 weeks, up to the full duration of the event.
