A Picture of a Dungeon Room With Cthulhu in it...

Also, in the theme of the above, here's some concept art for ALIEN...

Sunday Sphygyx

The Sphygyx, a man-like yet unrelated race, have human-like bodies with soft, short tawny fur and heads resembling a scaled smilodon. Their eyes are amber or golden orbs with no visible pupil; their scales continue in a strip down their spine, and are reticulated like a serpent in greens and browns. Both genders have breasts and nurse their young. Sphygyx society is based upon clans of matriarchal mercenary-nomads, and strongly values tradition, bravery, honor, and hierarchies. The Sphygyx despise cowardice, and many Sphygyx who wander Algol outside of the clans have been driven out by the open scorn heaped upon them for incident of fear upon the battlefield. They prefer battling in chariots, armed with bow, lance, axe and shotel. The Sphygyx worship their own small pantheon of Lawful deities, all depicted as female Sphygyx, and keep collections of small idols of these gods to set up shrines in their campsites or dwellings. Sphygyx do not understand affection or humor, and do not form strong interpersonal bonds; they have a reputation for being emotionless, aloof, abrupt, condescending, and rude among other races.

Thursday Technologies - Marcab Enclaves

The Marcabs were a powerful galactic civilization of human-like beings that existed at the same time as the Ancients of Algol. An oppressive, totalitarian people, they established several outposts in the Beta Persai system before their Confederacy collapsed due to war.

Although the appearance of their dress, architecture and technology is eerily similar to that of 1950s Earth American, albeit much more severe, stark, cold and also monochromatic, they possessed a much higher level of scientific sophistication and mastered the manipulation of psychic energies.

Several of their outposts on Algol survived as extradimensional enclaves. Accessed via armored, bunker like vault doors, these enclaves are notable for the complete absence of any color within the extradimensional space, with everything appearing to be be composed of grays, black and white. Usually these Marcab Enclaves consist of a towering, almost inhuman skyscraper like structure, usually with several shorter wings, surrounded by an endless flat plain of thick, closely cropped turf. It is constantly mid-day in these enclaves, the sky cloudless.

The few remaining Marcabs are usually immensely powerful Mind Wizards with access to powerful technologies. Their servitors are usually robotic or synthetic, although some have been known to abduct outsiders and force them to take part of their "society." It is said that all Marcabs are insane, and that some of them have been warped by psychic energies, mutating into inhuman monstrosities over the aeons. Some insist that certain especially loathsome psychic abominations that lurk in the darkest pits of Algol are descended from such Marcabs.
