Lithians, also known as Geokinetics, are a remarkable variant of humanity deeply attuned to Tetris's geological forces. Through centuries of evolution, their genetic makeup has granted them a profound connection with the planet's tectonic energies. Geokinetics possess the extraordinary ability to manipulate and channel the power of Tetris's crust. This affinity allows them to create seismic vibrations, shape landscapes, and even harness geothermal energy for various purposes.

Physiologically, Lithians exhibit enhanced bone density and sensory perception, enabling them to detect subtle shifts in Tetris's structure. Their bodies are strengthened to withstand the pressures of their unique abilities, and their innate connection to the planet grants them an intuitive understanding of geological phenomena. On the barren and enigmatic planet Tetris, Lithians are entrusted with the solemn duty of reshaping and fortifying the planet's landscape, turning it into a fortress of isolation and confinement for exiles and wrongdoers.
