Sure, I can write one up today. I suppose just basic info, name and personality and all that. Don't wanna give everything away right at the get go, y'know.
Alrighty, I wasn't entirely sure what to put in this so I just wrote a few paragraphs about them. Got a little long, you don't have to match it if you don't want to. :'D
Snowflake Obsidian were typically psychologists on Homeworld, before they were made obsolete by the rebellion, and Homeworld's turn to a more militaristic nature. Very few Snowflake Obsidians were kept in active duty to serve the highest nobility as a listening ear and occasional scapegoat. Most were reassigned to menial labor or shattered, since the Diamonds started seeing every gem as a potential soldier, and the weak and unable were not to be coddled and cared for, but replaced. Quickly.
A particular Snowflake Obsidian did not see the justice in this act, and quietly rallied a small, fairly capable group of other newly obsolete gems. Together, they devised a plan: Steal and airship and leave. Short. Concise. Foolish. Step one went off without a hitch, but the trouble began halfway through step two.
They had successfully warped far enough away that they would likely not be detected, at least until someone noticed a ship was missing, but the gems had not considered that the ship they had usurped was taken from a repair shop. They realized too late that the ship was losing integrity faster than they could possibly remedy it due to the prior warping, and the ship and its passengers were sent barreling into a nearby planet.
Upon impact, the gems found their ship destroyed and one of their teammates cracked beyond repair. After a moment of quiet reflection, they gathered themselves and continued on to find the new life they were looking for. They stayed close for a good hundred years, but eventually set off to find their own paths, leaving each other behind in good will and confident they would meet again someday.
Snow quickly found interest in the flora on their new planet. They devised how to grow their favorites and take care of them, often talking to them about her day and how the people in the town nearby are so curious and friendly. They often read books from the towns library, particularly psychology and recipe books. They're finally comfortable, but can't help the nagging hope for an adventure in the back of their mind.
