[Chapter] 49 [Entry] 
One might ask why Ruin couldn't have used Inquisitors to release him from his prison. The answer to this is simple enough, if one understands the workings of power. Before the Lord Ruler's death, he maintained too tight a grip on them to let Ruin control them directly. Even after the Lord Ruler's death, however, such a servant of Ruin could never have rescued him. The power in the Well was of Preservation, and an Inquisitor could only have taken it by first removing his Hemalurgic spikes. That, of course, would have killed him. Thus, Ruin needed a much more indirect way to achieve his purpose. He needed someone he hadn't tainted too much, but someone he could lead by the nose, carefully manipulating.
