I say we get a questline that awards a series of Reinheart-themed items.

Quest 1 reward: A stone statue of a glorious subligar (placeable in the fully implemented player/company rooms post-2.0)

Quest 2 reward: A crystal statue of Reinheart's character in a subligar. Again, it will be a room decoration.

Quest 3 reward: The actual subligar, aptly named "Reinheart's Glorious Subligar". It is a silver color while passive, glowing and color changing in active mode. (Think Rein's old signature before it got removed)
