On a distance world long ago evolved the Marshellowions,
The largest they grow is about 2 feet across they are one of the oldest space fairing species in the know universe, having no one to fight against they did not need weapons on their early ships so they focused in comforts for their large crews.
They were the first known species to develop artifital gravity, which they glad traded for the right to own their own home world,( no rent no involvement in future wars).
Although they love to explore space the biological need they have to be around their own kind in large number prevents them from setting up colonies on other planets.
If away from their home planet over a year even with I very large crew, they begin to suffer from extreme depression and must return home.
Any Marshellowions left completely alone for more than a day or so will lose all will to live and not move until either help arrives or it passes away.
Despite their small size their ships tend to be large in size, a small scout craft hold no less then 100 Marshellowions . few of their ships have escape pod for the thought of being alone with only a dozen of their own kind is unthinkable.
As they met more unfriendly rases they have kept up with weapon development as a way to ensure the safty of their home planet, they generally welcome all outsides that come in peace. And are quike to forgive invaders that stop hostilities toward then.
Although they lack any true arms or legs they can form phsodopods like ameba to control their ships and weapons, since these actions tend to be slow the controls on their ships tend to be too sensitive for other races to use.
Several time other races tried to invade their home world and fail, the extreme numbers of Marshellowions on the breeding rates make over whelming them impossible and since they cannot be alone or even in small groups for any length of time no slavers can use them making them a non-commodity .
They have been known to have killed off one race that refused to make peace with them, but little is known about them as their home world was left utterly barren after the war and the Marshellowions will not speak of the great tragedy.
A Marshellowions will gladly serve on any alien ship provided at least 30 more are there and the duty is less than one month, their early space exploring ships looked more like colony transports than exploration ships some holding crews of over 1 million.
With increased speeds and shorter exploration times crew sizes have decreased to 1000’s per ship when exploring, but they generally do not plan long missions with so few friends.
They are credited with finding the most races of all space fairers, mainly because they have been around the longest, but often do little more than stop to say ‘hi’ and return home to reunite with friends and family then plan the next trip.
If one could learn all they could about everywhere they traveled many powerful secrets could be learned. Although they would not deny access to that info to any of their friends the sheer volume of information is too great and poorly organized to find much useful data.
