Concept: “A gaping maw beneath an all seeing eye. How badly do want to die? In the first waves of the demonic incursion into C.A.U’s generators, corpses mounted around energy pylons with staggering speed. Infernal power fused together the pulsating remains which took flight to join the demonic hordes.”
Content: A creature searching for its Doomguy soulmate–to murder them, of course.
Writing: Vividly ominous descriptions and features situate the creature as at home in the CY world.
Art/Design: Layout centers on an image of the opthalmosphere itself, with creature details surrounding it.
Usability: Text has clear distinctions for different types of content and mostly contrasts starkly with background except for one block of text for a special ability that might be difficult for some to read.
