The Unseen One: "This particular globule has never been directly encountered. It only ever appears for very brief moments, and only in forlorn, hard to reach places like ocean beds, planetary cores, or the depths in the gulfs between stars. Nonetheless, its existence is confirmed - imperial savants learned to predict its appearances, and even described its signs in theory based on the subtle changes in certain arcane markers that follow its presence."
