"Go make thyself like a nymph o' the sea: be subject
To no sight but thine and mine, invisible
To every eyeball else. Go take this shape
And hither come in't: go, hence with diligence!"
-Prospero, The Tempest
The Inceran are an aquatic race of creature descended from octopi, elevated to humanoid status through the use of ancient magic. Such "animal men" were created for use as laborers and as test subjects, but now live wild in many places.
Inceran stand roughly 31/2 feet tall, and have rubbery flesh and a distincly octopus-like head. Color ranges considerably and changes with the creatures mood or whims. All inceran have a liking for brightly colored objects and jewelry.
Inceran speak their own tongue and common.
Combat
Inceran are intelligent, though cautious fighters, always having an escape route available.
Amphibious (Ex): Inceran can survive out of the water for 1 hour per 2 points of Constitution.
Ink Cloud (Ex): While in the water, an inceran can emit a cloud of jet-black ink 10 feet high by 10 feet wide by 10 feet long once a minute as a free action. The cloud provides total concealment, which the inceran normally uses to escape a losing fight. Creatures within the cloud suffer the effects of total darkness.
Jet (Ex): An inceran in the water can jet backward once a round as a double move action, at a speed of 200 feet.
Illiterate: Inceran are illiterate as a Barbarian, though in the incerans case, this cannot be bought off by taking a literate class. Because of this, inceran cannot take levels as a wizard, though other spellcasting classes are possible.
Skills: An inceran can change colors, giving it a +4 racial bonus to Hide checks.
Society
The inceran keep away from humanity for the most part, trading with fishermen or treasure seekers on occasion. Inceran druids or clerics are sometimes sought as healers and wisemen, but more often than not are feared. As inceran holy men, are less inclined to side with a human against the cruel sea than are human clerics.During the long day, Inceran are solitary and avoid each other except in crisis. During the long night however, inceran gather in large underwater caves heated by geothermal heat to dwell together. While there, they exhage in long debates and musical competitions. It is in this time that mates are chosen.
Inceran Characters
Inceran characters prefer the Cleric or Druid class. Inceran clerics typically choose the Water and Magic domains, and revere the Titan Oceanus, a male aspect of Tethys.
