Tu (Beta Hydri d), is the home planet of the Moraks.
Tu features only two continents, the larger being Kolsaviv, stretching from the near planet's South Pole to just north of the temperate zone. The lesser continental mass, Koltumiv is roughly the size of Australia, and is only slightly larger than the planet's four large islands which are often debated as to their status.
Kolsaviv features an equatorial mountain range that stretches into the continent's southwest, forming two distinct plateaus. A lesser mountain range near the northern Savivian Sea forms a natural temperate zone in the Planet's northern hemisphere with calm waters that facilitate trade among the Savivian kingdoms. The continent also features an equatorial peninsula with Mediterranean climate separated from the Kolsaviv Steppe which is defined by wide grasslands, punctuated by a large depression that forms the planet's largest desert. The cointent's Northwest features wide bands of temperate forests while its southern peninsula features a subtropical rainforest.
