We actually have:
Patriot Choker (not to be confused with the one you can buy freely i.e. the bracelet)
Manderville Earrings (Hildibrand)
Dalamud Horn
White Raven
That helmet that I forgot which looks like Onion Helm but blue (traded for unaspected crystal)
All those stuff are related to Meteor Project.

Arguably the Dalamud earring we got from last year event is also related, since in v2.0 Dalamud won't be up there anymore.
