The Grome (called by the Second Human Empire Xikki'loi Gooi'kilo) were members of the Axis of Empires. The Grome are one of the races permitted to compete in the Mutai. Grome can be distinguished from other races by their distinctive raised bone ridges above the eyes, small bone ridges at the top of the skull and layered "ears" that lie flat against the side of the head which afford the Grome with exceptional hearing. Like humans Grome have four limbs with five digits on both hands and feet. Their skin is rough, thickly patterned, pockmarked and pitted and comes in shades from very light to dark purple.
