The Elder Scrolls II: Daggerfall is the second entry in the Elder Scrolls series, and quite possibly one of the most ambitious RPGs of the era. Unfortunately, "ambitious" doesn't mean "not broken" and the game was almost comedically buggy.
While Skakmat is referenced in the game, it's never seen at any point. Skakmat is notable for being one of the few unused characters without a sprite specified in its political factions entry. Instead, a model would have been used. Skakamat does have a portrait as well as textures for what would presumably be his model. However, the corresponding model doesn't seem to exist in the game's data. According to his website, Mark Jones was the one that modeled the dragon and he claims that it was long since lost because of a server change at Bethesda. The only thing that remains are the textures and the Daedra Seducer's wing flapping animation (as said animation was recycled for said enemy).
