外观

爬行类的斯莱维伦人，就像是设法将蛇与地球人杂交后的产物：兼具类人的轮廓与形态，以及蛇类独有的所有次级特征。或许她们唯一真正欠缺的特征，就是头部和身体上的毛发。取而代之的是，从头顶延至后颈的宽阔眼镜蛇式颈罩，上面常装饰着精致的纹身图案，以取悦旁人的目光。颈罩内有小小的耳孔，使她们拥有惊人的前向听力，代价则是几乎听不见身后的声音。

斯莱维伦人的面孔带有口鼻般的突出部，拥有裂瞳和基本只是装饰用的鼻孔。气味其实由她们长而分叉的舌头传递，不过它比蛇类外观所让人想象的更宽、更肉感。一片异常丰满的下唇赋予她们许多人眼中性感的外貌；但在那张看似柔软、仿佛无齿的嘴里，藏着两根可伸缩的针状毒牙。好在斯莱维伦女性已能极好地控制相关肌群。

斯莱维伦女性身体的其余部分也如人们所想。柔软鳞片自头顶铺至脚跟。一对类人手臂末端的五指双手，使她们能兼容大多数银河武器。跖行的双腿与双脚则让她们能穿上地球时尚带火的高跟鞋大步行走。最显眼的例外是她们的乳房，其重量足以媲美吃得最饱的拉恩人；另一个则是典型的爬行类尾巴，长得能拖在地上，用以平衡她们过于丰满的胸部。

这些曲线玲珑的蛇女热情拥抱核心社会的世界主义生活，因此成为着色类身体改造最大的消费者之一。闪耀的金色鳞片和闪烁的生物发光表皮同样常见。DNA 分析暗示，她们或许曾是棕色的，却永久改写了自己的基因组，直至明亮、炫目的色彩成为常态。

起源与生物改造

斯莱维伦人的生物学完美展示了基因改造如何让文化争端最终催生全新种族。斯莱维伦人原本是卡塞利人，但在接触 U.G.C. 后，思想分歧将该种族分成两派。一派认为，依靠其他种族雄性的性欲，族群能够活得更舒适；另一派则希望维持原貌，凭自身本领、不经改造地兴盛。

前者积极推动改造自身的计划，借此利用奎坦人等活力过盛的哺乳类繁殖者。卡塞利毒液被精炼为无毒且可被彻底代谢的物质。其效果也被增强，可抑制自主肌肉活动，并微妙地改变大脑化学以降低克制力。人们加入新的化合物，暂时提高弹性，使斯莱维伦人的喉咙能容纳天赋异禀雄性的弯曲。最后又加入细胞生长剂，以迅速修复注射所造成的损伤。

Of course the proto-slyverens did more than modify their venom. They changed their very body shape to be more familiar to their “prey”. Bipedal legs made them seem less alien. Mammalian-style breasts offered something to draw the eye of prospective “seeders,” and with their long tails as counterbalances, they’ve been able to grow some of the biggest chests the galaxy has to offer. These seductive snake-women altered themselves to appeal to the masses, and judging by the popularity of slyveren blowjob holos on the extranet, they succeeded with gusto.

Time has only given the slyverens more opportunities for self-improvement. In modernity, they boast a numbing coating on their fangs, additionally salivary glands along the inside edge of their lower lip, hyper-sensitivity to pheromones, and an aptitude toward psychic ability that left terrans in the dust two generations ago. Fully 50% of their population is considered to have some degree of psychic talent, with projections estimating race-wide telepathic capability in 100 years.

Reproduction

Slyverens do not reproduce utilizing penises, like most races. Instead, a slyveren woman will produce a fist-sized egg once a year. When mating, she press her vagina to her lover’s, and specialized muscles will eject the ovum into her mate’s channel. Hard-wired reflexes kick in at this point and draw the egg all the way into womb, pushing the second slyveren’s egg out to trade places with the first’s. This exchange triggers the release of semen from a combination ovary/gonad gland until fertilization occurs.

A full incubation term lasts five months, after which the egg will be roughly melon-sized. Hatching takes four to five months, much longer than the Caesselis they originated from. Slyveren younglings emerge tiny but capable of basic locomotion. Milk, an adaptation stolen from other races, provides sustenance for them well into adolescence. It is only after maturation that they switch to the licentious food-source that has given rise to their fame - and only after lactation stops does a slyveren mother’s body begin to produce eggs once more.

Unfertilized eggs are expelled from the body after a few months. The more debased among high society consider them to be an exquisite delicacy.

Current Intragalactic Relations

Slyveren-controlled space is small, mostly centered around their originating system. Colonization by more aggressive races has found their territories surrounded, and the increasing number of protein hunters in the core has reduced demand for their services to record lows. Shrewdly negotiated trade deals by Galotian-controlled holdings have crippled most local industries to leave the slyverens as a people in crisis.

The 14th Planet Rush brings with it a chance at untold wealth and riches, and the slyveren government has responded by aggressively subsidizing would-be rushers to colonize primitive, unincorporated planets. Galotian rushers are encouraged to avoid contact with slyverens in the wilds. Males and hermaphrodites should exercise caution. Thirsty slyveren will disregard consent laws in favor of a fresh meal, should they find themselves in the wilds of a rimward planet.
