The Sesheyan from Alternity

Hi Folks, This is the first post about the Alternity alien species. I’ll make a post for each, then gather them together into a pdf and post it over on

The Sesheyan have long thin tails with a fanned membrane at the tip. the underside of this fan is brightly colored in males. Males also have larger ears with unique markings. The Sesheyan sense of smell is located in pits under the eyes. Their ears are used to fan air across these pits to enhance scent detection.
Females give birth to 4-6 young on average. The births happen in specially chosen communal birthing pools. The young are born in what humans call the tadpole stage, they are about a foot long, with black limbless bodies and a large fleshy tail. The young consume the natal jelly that is excreted as part of the birthing process. As they grow they change to a diet of insects and vegetation provided by the clan. They triple in size over the summer months, they then develop front limbs and dig into the clay banks of the pool where they form a chrysalis and metamorphosize into their adult forms over the course of the fall. The second birth, where they dig out from the clay, occurs at the start of fall. The young are about half the size of an adult Sesheyan, their wings are fully formed and after approximately a month they are able to migrate with the adults to the wintering grounds in the south. Births are communal and the clan raises the young as a whole.

Sesheyan culture revolves around the complex seasons of the hunt. Their homeworld, Sheya, is a moon orbiting a gas giant. The complex orbital mechanics of Sheya and the other moon’s revolution around the gas giant, that system’s revolution around the star and the movements of the planets are well known to Sesheyan shamans. With this understanding and the migrations of prey animals Sesheyan see the universe as a series of cycles. Birth to death, summer to winter, their universe fits well into their cosmology.
The hunt factors into their culture as their wanderlust. They are always hunting new grounds, looking beyond the next valley. Wandering far in search of food or tales is considered heroic. Conversely those that do not return are not spoken of and VoidCorp xenologists translated the term for them into “ghosts”, although the terms is closer to “completed” in the Sesheyan mindset. Sesheyan death rituals take into account the wanderlust. Funeral pyres are set on the highest peak as the deceased is sent on one last journey. The dead are given a new name which is used when invoking their aspect, and their life names only are used when relating tales about their lives.

The wanderlust informs the interaction between clans. There are regular meeting grounds on the migrations where clans meet exchange members and separate. Those that leave one clan for another are given new names, when talking about their time with the original clan they are referred to by that clan name, their new experiences form under a new name.

The concept of cycles influences the Sesheyan way of thinking as well. Ancestors are thought to be part of the mythic. Sesheyans invoke aspects of the mythic to inform their thinking and actions. This triggers a change in the mental architecture and a complex release of hormones. Shamans keep the tales of the archetypes alive and educate the young Sesheyan in those most useful to the individual and the clan. (Many Sesheyan have the Faith perk to represent the calling on the mythic.)

It was purely by accident that the VoidCorp mentality fit with that of the Sesheyan. When the first contact consuls explained that they could venture to the stars, the Sesheyans signed what they believed was an agreement to join the VoidCorp clan. Being given employee numbers was just getting a new name with the new clan. Over time their shamans came to realize they were being exploited and that those who left were not being treated as equals in their new clan. The Sesheyan that are taken are given special ghost names and considered lost to the hunt by those remaining on Sheya. VoidCorp even pledged that those dying off world would have their bodies sent to the nearest star to be incinerated. That is but one of the promises by VoidCorp that were never intended to be kept.
VoidCorp has studied Sesheyan culture and indoctrinates the ghosts into new archetypes of the VoidCorp “clan”. The Good Worker, the Humble Servant and others have been invented to keep the new employees in line. The shamans know of this and make a special effort to equip the young adults with aspects from the mythic that rely on subterfuge and devotion to the Sesheyan species. What’s more, the VoidCorp Sesheyan have begun to craft their own archetypes from their own communities, and even taking mythic archetypes from human culture without the approval of VoidCorp.
