Shalidor the Archmage is, according to some sources, supposed to have found the secret to existence that he referred to as "Glamoril". There are legends also of him performing incredible feats of magic that are very much like Tiber Septim's "shaping" of Cyrodiil. For example he seems to "will" the city of Winterhold into existence, and took on, by himself, an entire legion of dwemer (which is how he discovered, much to his surprise, Spellbreaker and thus developed a spell based on the concept).

Is Shalidor's Glamoril actually CHIM? It would make a bit of sense.
