My (short-lived) topic in roleplay discussions leads me to believe something like this is acceptable, though I'm not so sure there's all that much interest in it. But I'm going to post it anyway.

Note: References to Whisperer are to that monster's original form as detailed here.



Name: GrEO (Great Elder One) or just 'Greo'

Species: Unseen (Whisperer's species)

Gender: Male.

Age: Unknown (stopped counting after 1000)

Dimensions: Variable - Usually about 20 feet in diameter and 6 feet thick, but can squeeze down to about one-half this size for short periods.

Weight: N/A - Gravity doesn’t seem to affect him and even his mass is abnormally small for his size.

Skin Color: Hazy Translucent.

Skin Texture:
Body: Smooth but waxy.
Stinging tendrils: Soft and feathery, yet can produce sharp pains when they strike at speed.
Grasping tentacles: Rough and bristly due to the many tiny barbs that secure his grip.
Phallic tentacles: Similar to human skin, though a bit rubbery.
Trunk Maws: As the body mass, however, their tongue-flaps are rough - like a cat’s tongue.

Number of Tentacles: 40 total: 8 stinging tendrils, 8 Trunk Maws, 8 Phallic tentacles, 16 grasping tentacles.

Number of Cocks: 8

Cock Size: 16-inch erectile tips, but mounted on 19 feet of prehensile tentacle; variable girth from about the width of a finger to that of a man’s wrist.

Method of Attack: Greo is so old that he can no longer efficiently hunt. He has settled down on Vanejin and opened up a shop of sorts. He sells his semen to those who appreciate its healing and life-extending qualities. He'll take currency, but often prefers trade such as a nice vivacious slave girl or two (to feed on - the actual transferal of ownership would buy more than just a dose). Female clients can get a significant discount by offering themselves up for trade. Feed the beast once and get an extra dose to take home . . .

Motivation: Energy vampire. Greo feeds on the life-force(s) of female (or mostly female) sentients, psychically absorbing the energy as it flares during orgasm.

Distinguishing features: Due to advanced age, Greo's originally transparent body has become hazy. His fluids swirl with ribbons of color like an oil slick in the rain.

Description:
Like Whisperer, Greo is one of the Unseen, a race of alien psychic parasites that feed on the life forces of female sentients. However, he has reached such an advanced age that he is no longer transparent. His main body mass is a hazily translucent umbrella shaped sack of rainbow-colored fluid roughly twenty feet in diameter which floats in the air by unknown means. Greo is considerably slower than Whisperer. His great bulk and advanced age have taken their toll on his mysterious method of propulsion. He can only manage a speed of about 3mph.

Forty specialized appendages extend from the underside of Greo's main body mass. Each one has a reach of about twenty feet and full range of motion. There are sixteen rough, bristly grasping tentacles which serve as his primary means of manipulation; eight phallic tentacles the last sixteen inches of which harden like erections when aroused; eight trunk-like tentacles that end in circular orifices which contain four long, dextrous tongue-flaps each; and eight thin feathery stinging tendrils that can deliver varying degrees of bio-electric shock. He no longer produces the Unseen's trademark venom.

(I looked for a picture to give at least a vague impression of what Greo looks like, but this is the best I could come up with)


Capabilities:
Greo is an accomplished telepath. He can easily sense the surface thoughts and emotions of those within 1000 feet. In fact, he sometimes has trouble screening out the stray thoughts of those close by (within 30 feet), so he often takes refuge in his 'Well.' Though he still has his psychic lure, he no longer uses it, preferring to project his thoughts directly when communicating. His psychic skills are advanced enough that he could erase or alter a sentient's memories if he so chose (assuming they had little or no psychic defenses), which is a service he might offer in the future.

Greo's feeding patterns are the same as Whisperer's - he requires his 'prey' to orgasm (usually several times) before he can truly feed. Each climax weakens her life force’s connection to her body and frees a little burst of energy, which Greo eagerly absorbs. In some ways, this process is like cooking for the alien and the orgasmic bursts are like little tastes. When the ‘taste’ is right, he begins to feed, psychically drawing out his victim’s life force. This causes the woman's climax to extend unnaturally, lasting for the duration of the feeding. Such a feeding lasts for several minutes and does not end until Greo is full or until the victim is on the very brink of death. Either eventuality triggers a massive ejaculation from the beast. Greo's semen is even more potent than Whisperer's. Not only does it support the victim while she recovers from the feeding, it heals all ills. Even lost limbs could be regerated. When given to a healthy creature that has not been drained, Greo's semen also reverses the aging process. One dose (considerably less than the amount he ejaculates) grants about one extra year of life to a human recipient. Effects vary considerably by species. The fluid also produces a powerful feeling of euphoria that lasts up to 24 hours. Some sentients buy it just for this effect.

Special notes: When aroused, Greo's phallic appendages constantly drip large amounts of pre-seminal fluid. This substance is a less potent version of his semen, and has an analgesic effect. It dulls pain (without affecting other sensations) as well as granting the victim’s body increased resilience so that she can endure the monster’s assault ‘undamaged.’ Not that any such damage would survive the effect of his semen in any case.

History: Long ago, the Unseen who has come to be known as Greo was like Whisperer; a hunter constantly on the prowl for his next meal. Centuries before the founding of Shokushu campus he prowled the space lanes, feeding on whatever feminine morsels he could catch. He was so successful throughout his long life that he grew to an immense size. But eventually his age and bulk slowed the alien and he began to lose his natural transparency. He faced a slow painful death by starvation.

Luckily for Greo, he encountered a strange alien 'scientist' who wished to study the capabilities of the Unseen. The being called himself Nebthraxus and claimed to be researching immortality. For years, Nebthraxus would capture young women and feed them to Greo so that he could collect some ot the Unseen's semen for his experiments. During this time, Neb and Greo discovered the anti-aging properties of Greo's semen (ironically this is something Neb forgot after he succeeded in becoming immortal). Eventually, Neb's studies took him in other directions, but Greo, now armed with the knowledge of his semen's value had a plan: He sought out rich and powerful patrons, appealing to their vanity and offering longevity in return for women to feed upon. His favorite clients were all female, since he could 'dose' them directly, but he never spurned those male clients who offered up female slaves or captives. The venture was so successful that Greo eventually started charging fees as well, amassing a good deal of wealth.

As the years passed and Greo's age became even more advanced, he settled into a shop of his own. He named it the Well of Life and there he continues his business, selling his miraculous semen to any willing to buy or trade for it. He still makes house-calls infrequently (mostly for favored female clients), but otherwise spends most of his time in the Well.

Slaves: Greo currently owns one (NPC) slave: A 'catgirl' named Kyera. She was given to him as payment for a large order and has served him faithfully ever since. She actually loves her Master, finding him much kinder than most. Aside from serving as sustenance when business is slow, she also works the shop-front, greeting customers and arranging meetings with Greo.

Pretty intriguing, and I like all the work that went into thinking up his story.
