Trackies were a breed of humanoid that lived underground. They were intelligent, spoke their own language, and had a society; they subsist on whatever they could catch (mostly fish), using crude spears, knifes, or tridents.
Trackies rarely top five feet; they had hairless skulls, large ears that are set further back than normal, large protruding eyes, a slit nose, and a lipless mouth filled with rows of ragged teeth. Their skin was pallid white with a tinge of green, and their blood was faintly phosphorescent. They had vastly improved senses of sight and hearing, enough to see in low light and hear even the slightest sounds.
