Controller



''Note: This article is about the tool created by the One Concern that is able to control Ivory-powered machinery. For the ancient tools used to control Planet Spines that the Concern Controllers frequently latch onto and manipulate, see: Spine Controller'' A Controller is a One Concern invention that is able to control Ivory-powered machinery. They were created by the Concern long ago by harnessing or mimicking Eyes, which have the ability to control all Ivory. They are frequently used as weapons. While not deadly on their own, they can be used to possess Ivory machinery to make them act autonomously or turn them hostile. They can even control Spine Controllers, though the Concern have not fully realized how to do so, limiting their ability to use them.

Two variants of the Controller that can fly and attack directly as well as controlling Ivory machinery are the Coptroller and the Conroller.

=Research and Production= The Concern's Controller technology dates back at least hundreds of years, back when Father was the current Medium. A research lab, now called Dark Cave, existed under the Darland Ascent. The Concern discovered the Eyes deep underground and tried to harness their ability to control Ivory. The Concern were able to produce a large number of controllers in the underground facility before an unknown disaster struck. The Concern quickly sealed off the cave, and all those left inside of it perished due to unknown causes. Many of the controllers produced were left under Darland Ascent. The Concern still had a sizeable supply outside the facility, but when that started running low, they had to send soldiers into Darland Ascent to retrieve more from the stock that was left behind.

=Attacks= Controllers will never attack directly. They will primarily latch onto something made of Ivory and use that object to attack, or they will spawn spikes to turn into a Coptroller or Conroller.

=Weakness= Concern Controllers are invulnerable while attached to Ivory machinery. However there can be methods of knocking them loose, usually by doing damage to the object they are attached to. This comes into play in several Boss fights. Once they are floating freely in the air, they can be damaged by any weapon.
