Beregale

Description
While not a classical "hothouse" world like Venus, Beregale is scarcely more hospitable. In addition to being the closest to the star Tasale, its core contains many radioactives and other heavy elements. These increase the heat of the planets and drive volcanism. Beregale's crust is too rigid for plate tectonics to function, and the planet will go through cycles in which the pressure builds to a massive super-volcanic eruption. These spew ejecta over thousands of kilometers, leave caldera a hundred kilometers across, and spew enough molten material to repave entire continents. The last such event was 812,000 years ago; the current rate of outgassing from volcanic hot spots suggests another will occur within the next 10 millennia.
