Dellah

Dellah, a resource-poor planet on the fringes of Earth Empire space, was home to St. Oscar's University in the late 26th century. Bernice Summerfield lived on Dellah for a few years. It is an M-type (Earth-like) planet orbiting a single star, and has no moons. (BNA: Ship of Fools)

A Watery World
Dellah is mostly covered by temperate oceans, dotted with islands. Its largest body of water, the Silvasic Sea, takes up most of the temperate zone (between 23.5°S and 66.5°S) in Dellah's southern hemisphere. (BNA: Dry Pilgrimage)
