Mylo Xyloto is a comic book series created by British rock band Coldplay and filmmaker Mark Osborne.

[1] On 10 July 2012 the Coldplay website announced a six-part Mylo Xyloto comic, with the first issue to be released at that week's Comic-Con.

[2] Published by Bongo Comics,[3] the story followed the tale of Mylo, a 'Silencer', who, in the words of co-writer Mark Osborne (filmmaker), is a part of a "war against sound and colour".

They have a military police force recruited from Silencians known as the Silencers, which are taught to enforce the Irdok's rule of law, which is known as Chromatic and Acoustic Level Management (CALM).

To make up for the lack of colour and sound in their world, the Silencians use a tool known as the Hypnofeed, which constantly feeds them with visual and (ostensibly) audio stimulation.
