Yvara was the homeworld of the Yvarema species. It was located just inside the Kathol Rift. The planet had a varied topography, with ice and snow capped poles, vast desert plains, and fungal-covered fields. Three oceans covered the planet, and each of the continents were ringed by mountain ranges to create a natural barrier. The planet's indigenous species, the Yvarema, lived in underground warrens just north of the planet's equator.
