The fanfic I'm writing is so that I may get into the swing of literature. A test story if you might like in the Mass Effect Universe. Please prepare for a long text because there's a lot of trivia here.
Now what I need is in this hypothetical scenario; humanity is a techno-organic race and is one of the few in history to enter the second stage of Singularity. This culminates in them creating an instrumentality effect a la Evangelion style, minus the giant naked girls and traumatized teenagers, with a twist. They all die and merge into a colossal eldritch entity.
This is what I have made so far.
Now the firm I've made so far has to do with humanity in some way. The body: it's humanoid in proportions due to it being a union of humanity. It has no skin, just transparent liquid diamond muscle with iron red striations, its cardiovascular system uses superheated liquid iron as blood. The bones are composed of a calcium silicate crystal that is shiny and white. Then it is covered in an obsidian bone plates that hide certain parts of the thing. At its center lies a red ruby core that pulses energy throughout the body. It has a halo that sports large number of angelic wings composed of red solar plasma with blue tips on them. Very much like Magnus the Red's wings just made of solar flames. It has three burning eyes. It also has throughout the body circuit like patterns due to humanity's techno organic nature.
The colors. Red is a psychologically active color on humanity (aggression, sex, blood, strength, virility, vitality, etc...) as such its the most abundant on it, likewise blue is our general favorite as it is present in the tips of the wings. The fiery and luminous nature of its wings and 90% of the body come from the fact that humans are creatures of the light and being in absence of it for long periods of time messes with our minds. The wings symbolize humanity's long wish for flight. While it may not look that impressive its effect its mostly on the mind of the observer.
The story is quite sometimes written in the eyes of the aliens. A human sees this thing and goes "That's so beautiful.... am... am I home? I'm home....". An alien though sees this thing and can only express disgust, horror or revulsion. For us is a warm welcoming light that never judges, never excludes you and always protects you, like a mother, a father, a brother, a friend. It is in essence... home. For aliens though it's an incandescent red light so pure in its form and sentience that its a perversion of all that it associated with, it excludes you from all warmth and you only feel the unrivaled heat and alieness from it.
Its name is Zha’asladroth, which translates to the Crimson Daemon Star of a Thousand Winged Crown. Thats it thats what I have so far.
I want to make a cosmic abomination from humanity. So how can I make it a more eldritch being?
