The Ship of Heroes site has been updated with a new blog post to unveil the game's fourth villain group called the Red Sigil. In addition, the role of magic in the game is explored, most particularly focusing on The Attuned, a "general-purpose faction" that is centered on mages and learning magic. Within the Attuned, the "shadowy cult known as the Red Sigil" hides.
&The mages of the Attuned hate the Prometheans above all others, and this antagonism is reciprocated. The Attuned fundamentally like the ship as it is. Even the Red Sigil only want to seize control of the ship's political system and revenues; they would be happy to have super- powered subordinates if they could effect a coup. The Prometheans want to wipe out the supers, restrict magic to a single type, forcibly convert all mages to cyborgs, and imprint the insane views and dangerous powers of Dr. Cornish onto all of the Attuned – and when Dr. Cornish complains about abusive, egotistical heroes, he often cites famous mages as examples. Philosophically, the Attuned are all about hard work and respect for a meritocratic elite, while the Prometheans are all about reckless innovation and a deceptive brand of populism.
