Big Bad Roll Call

The Guardians of Zion
 * Chapter I has the aptly named King Usurper, a once good man corrupted by dark spirits while exploring the far arctic north. Murdering his friends, the rightful king and his council of good wizards, he plunged the Middle Kingdom into an era of darkness under his iron rule, before being overthrown by a rebellion headed by his own son
 * Chapter II features an interstellar Empire that had laid claim to the entire planet in the past, now returning in the modern age to assert their authority. However, the actual Emporer never makes an appearance and High General Absalom is the face of the Empire on New Horizon. Later stories reveal that the Emporer is merely a figurehead for the High General anyways, who calls all the shots (Including abandoning the conquest of New Horizon, once the heroes make it clear it will cost more resources than it's worth)
