Shouldn't this be in the K2 forum?
As to the question, I also perceive the mystery and sadness. I also get a sense of isolation, and also melancholy. The isolation may be a result of playing K2 where the Telos Academy is on one of the planets poles, in the middle an ice wasteland. The melancholy, however, I think is an intentional objective on the composer's part, specifically to reflect the state of the Academy at the time - empty, skeletal, and having something very, very wrong about it.
