Gonna go ahead and put this here for your leisure, xanderK.
At one point, when the Observatory first came out (before it sold potions), there was some word from S2 that certain things were being tested out for it. While I love having the potions there, I can't help but feel that there was something more intended for the Observatory.
Can you say anything about what might be in store for it, or if anything still IS in store?
Your feeling is correct and there was something more intended for the Observatory. We still intend to do more with it in the future but I'm not sure when that would be.
