The Special Event Chest is given once you've completed all 30 of the event quests during the event time frame - the chest will contain a mix of talismans, tools, energy boosters, etc.

The Chests from past Special Events are available in the store after an event ends contain a random Collection Item and Fixer for their respective events.

And yes, the Artifacts would come from those past event chests. Sometimes they also come as bonus chests if you purchase one of the Bank offers with real world money.

You can also wish list them and friends may gift them to you if they have extras of those collections. There was a glitch before where those artifact fixers were giftable and didn't come out of your inventory so some older players have them in bulk.
