Planet of Origin: Irath, a planet with two moons, one of which was habitable, oribiting the star Vysu in Votanis star system in the Milky Way Galaxy, which they shared with the Irathients and the Liberata. Irath's sky has a red color to it and may have had a higher concentration of Nitrogen then Earth does
Sensoth are strong, large and tall humanoids with extended lower jaws and a large amount of hair on their faces. They are their homeworld's species with the longuest lifespan, able to live over 200 years. They prefer to live at a much slower pace than others, speaking and acting slowly due in part to their long lives. Due to their long life they are always planning out things. Not without humor, their practical jokes are always designed to unfold over time.
On Irath, they lived in the Great Tarnalin Forest and had trade relations with their homeworld's other. They were subjugated by the Castithans and forced into slave work and conscription in their armies.
As of 5000 years ago, they fled their homeworld along with all the other species when their system underwent a stellar cataclysm.
