Overlord(Ship)

Overlord is the third playable ship available in the game. Unique to its gameplay is the feature that the only weapons available are swords. Because of this, its default weapon is also a sword. The default weapon acts as a sword without keywords, so you are still incentivized to pick up new weapons for all the same reasons you would normally.

Story
At some point in the past, Overlord, presumably the leader of the rebel faction, challenges the Grand Pyromancer's authority. The Pyromancer desires a demonstration of the Council's power against the rebels, which Overlord contests.

Later, Overlord arrives as the 10th Visitor to the Facility. He fights his way deep inside, reaching the sixth floor and the damaged Machine. While managing to harm it even further, Overlord succumbs to extreme damage. Before the coup de grace is delivered, the Chaos Ship knocks him out of the way, taking the hit for him.

Presumably because of the damage dealt to him, Overlord is forced to occupy a larger war craft. It is unclear as to how this transferal takes place. It is also unclear, after this transferal, as to whether Overlord is under the influence of some other power, forcing him to guard the sixth floor of the Facility, or if he does that of his own will.

Later still, Null arrives in the Facility and eventually reaches and destroys Overlord.
