OK, party is over! Back to the old-fashioned settlers.
As a small extra surprise is that 2 of the adventures are now available at the trader for a (few) handfull of gems:
Update 31/07/2013: loot is added to "Old Ruins" & "The Shaman". For details look at both adventures.
Needless to say they are now added to the list of permanent "Guides" here on the left & to the lists of "where to get adventures?" & "Loot overview" in the top bar.
As you might noticed: the "20th Anniversary event" hyperlink in the top bar & the "Guides"-list has been moved to the "Past events"-list (down on the left-side).
