Sen is a very mysterious nyulop. Arriving at the end of The Time of Kindreux, Sen silently slipped into Whistler's Crest's seasonal residencies, observing the others from secret hiding places. This lasted a few days until finally he was found and properly housed. From that day on, his odd tendencies didn't lessen, more so it was amplified. Most finley stay away from him, as his piercing eyes unnerves them, never letting up on watching every single one of them silently. He doesn't seek out company ever, but if there comes a brave enough finley to do so, maybe they could unveil this strange nyulop secrets.
