Us

Humanity

Oh, My friend, we began on quite the speck of dust. We had it all: a thriving ecosystem, air, water, and land to expand. Confined to old blue, we fought among ourselves over what we didn't possess, despite its obvious abundance. Something united us before it all fell apart, but our history has some missing pieces, the most irritating kind of puzzle.
We know not why we ventured out, nor how we came to lose our speck of dust. Theories are as common as the cold.. For me, it's simple. Needs and wants are not the same thing. Desire is relative. We looked to the sky, and we felt a familiar sting. Earth, as it was, offered little to satiate this hunger. Why would it? For the better part of centuries, all scientific endeavors centered on leaving it.
Perhaps we destroyed it out of spite, or maybe something came and did it for us. The records we have from this dark time mention a phrase, one that directly references the fall of Earth: "We broke into heaven," whatever that means. Religion by this point was at an all time low, so I doubt it's literal. Perhaps it's a code, or some sort of trigger. None the less, all those who survived the earth's fall know the phrase well.

The Diaspora

Humanity scattered about the void. Some ventured in premade Arks, vessels made by many of The Origin System's rich and powerful. Arks only housed scientists, cultural figures, doctors, and engineers. Only those believed to better mankind were allowed aboard. How does someone make such a decision? Does a farmer not turn the gears of society any more than the famous chef who uses their crop? What of the one who repairs and operates the machines a famous engineer created? It matters little. When the Arks arrived at Safeharbor, we felt the void they once filled all the same.
The Arks took vast collections of data, much of which I sort through to find what can be of use. The data neglects to mention how the earth died, or why our colonies in the system were unsuitable for relocation. It was a massive effort, but not all humans were willing to stay behind. Most lived in struggling nations, those unable to produce an ark.
They began construction on fleets of transports. A few of these vessels made it to Safeharbor. They were poorly constructed, poorly designed. They were thrown together in haste. The safety checks were ignored, as if someone was in an awful hurry to leave. Those that didn't make it to Safeharbor drifted. Some found other worlds, most of them claimed by one species or another. Others found a home on space stations, the residents ignorant of how new we were to the galaxy.

Biology

When we were discovered, it caused a panic. We were gathered up, studied, and experimented on. We were isolated, placed in zoos and farms across the galaxy. As cruel as these projects were, they have revealed much about us we didnt know. Humans who left Earth are not quite the same as their ancestors. Evidence of genetic manipulation exists, tampering centered around our senses, the density of our skin, and bone.
The changes were small, barely noticeable, but some had a profound effect on our species. Other races call us "twitchy." We avoid staring for too long a time. Those responsible for this tampering instilled a delayed reaction, like an overexposure effect. The more we stare, the more our eyes adjust. The more we stare, the more we see.
This can include Subtle changes in elevation, discoloration, asymmetrical forms, and even non-visible light. It's why stargazing is such a common pass-time. Our neighboring nebula, called "The Eagle Nebula" back on earth, is a sight to behold when the eye adjusts. The vibrant colors radiating from it are mesmerizing, We now see what took special equipment and image manipulation to see before.

Touch

Humans have always been social creatures. We need to connect, to experience Intimacy... to touch. I do not know if it was intentional, but genetic modification to our sense of touch did more than enhance our bodies. It's common for humans to express an aversion to physical contact, not just with each other, but with anything.
Humans are significantly more sensitive to touch than many other species. For us, tactile stimuli is abrasive. Humans often wear gloves developed with interior layers of aerogel to avoid the feel of fabric. We are so sensitive, most of us suffer from a debilitating case of haphephobia.
It's a horrible fate to desire your lover more than anything else, but be unable to muster the will to hold their hand. We often partake in Stargazing, our favorite passtime. The visual overload is essential. It overwhelms all other senses, allowing for the simplest of life's many pleasures.
