Depends which you have. But Exodus' Lair seems to be the rarest, followed by I think Chaos Shrine. Blackthorn's Castle and Twin Oaks Tavern are next I believe. Though I am prob the only one that thinks Twin Oaks is rarish at all. After that they are all pretty common. Though the Towns and Shrines are older.

That picnic basket is prob about 7m, and its not glacial blue. Its more chaos blue and black.
