One of the great purposes of a lair is to act as a record of achievement. We see this canonically in places such as the Fortress of Solitude and the Bat-cave; both are full of trophies of past battles and campaigns. The current lair items on offer are fine indeed but the idea of a lair could be greatly enhanced by the availability of trophies and not just furniture. Imagine, for instance, that every raid dropped a momento every time you first completed it. Be it a chunk of the defeated robot villain, a postcard from Kahndaq or something similar. More or less the equivalent of the giant penny in the Bat-cave. Perhaps a series of small display cases with a memento from each raid in each. This adds a new aim to the game; collect the entire set (which you do when you finish each raid). Make them non-sellable and non-tradeable so people can't claim trophies they didn't earn and I believe lairs could be much more a record of achievement and progress. On a related note: On the old forums I suggested that each Mentor should grant, upon completion of each level 30 mentor quest, a distinct item to that character. Superman may have a shard of kryptonian crystal, Batman a batarang on a display stand and so on.
