    Gravs are short stocky humanoids who have the ability to manipulate gravity. They mine ore and gems from unclaimed asteroids and moons. A Grav is short, squat and square, averaging 4 feet tall and weighing as much as a full-grown Half-Orc. They have broad thick shoulders, and flat circular leg's, their heads appear drastically small when compared to the rest of their bodies.

    Combat: Grav's are a peaceful race, intent on their mining and leaving other races alone. If provoked, however, grav's utilive their special abilities with great skill. Grav's will typically demonstrate their gravity manipulating powers to would-be attackers. If this warning is ignored the Grav will typically seek suspend their opponent and incapacitate him.

    Gravity Reduction (Su): At will, a grav can decrease the effects of gravity by 25% per round on a single object or individual no greater than one size category larger than the grav. After four rounds of this the target becomes weightless and begins to float. This is considered a move-equivalent action, maintenance of the achieved level of reduction is a free action that lasts until the grav decides to tend the effect or is rendered unconscious. This effect has a range of 60 feet.
    The grav have not control over the course of the weightless creature and thus it might drift out of range and plumet into the nearest gravity plane. The target can attempt to avoid this effect by suceeding at a Reflex save (DC 10+Level). Use of this power does not allow a grav to wield weapons that are too large for it, as such limitations are a subject of mass, not weight.

    Grav Traits (Ex): Gravs benefit from a number of racial traits.
    &    Darkvision up to 60ft.     &    Grav are automatically immune to the effects of the Grav's Gravity Reduction power.     &    Gravs bear an intense hatred of metal-eaters such as Silatics, and Rust Monsters, and gain a +1 racial bonus to attack them.

Skills*: All Grav receive a racial bonus of +2 to all Craft, Knowledge, or Profession rolls regarding Stone, or metal work or mining.

Grav Elites     Grav Elites are the absolute leaders of grav society. They stand as a breed apart from the "low" grav. They are thinner than their worker minions but are still squat. They wear refined, foppish clothing and seldom sully their hands with manual labor. The Elite are the only Grav's traditionally allowed to pursue Spellcasting classes, usually Wizards. It is these Elites who pilot the Grav Argosy, their asteroid-like Spelljamming ships.
    An Elite Grav's typical ability scores are Str 10, Dex 8, Con 12, Int 13, Wis 8, Cha 11. But otherwise bear the same powers and traits as the common grav.

Grav Characters
    On rare occasion, an individual Grav may seek to leave the strict class structure of the Grav. Whether this is the escape the near-slavery of the low grav, or an elite seeking to sample the riches of the greater universe. A "Low" grav's favored class is Fighter, while an "Elite" grav's favored class is Wizard.

In The Spheres
    Grav society is strictly hierarchical. The elite order the miners (workers), who obey almost without thinking. Miners who question this structure are promptly "brought in for questioning" and moved to a position "better suited to their talents" – servitude to some minor elite. This is ultimate shame.
