Pelagia Province was a section of the Tapani Sector ruled by House Pelagia. The systems Betolio, Dampher, Grella, Lorenz, Kamper, New Javis, Setolio and Netolio were in the Pelagia Province before they were ceded to House Calipsa after the Mecetti Purge. During the Galactic Civil War the province contained three systems and two inhabitable worlds.
The Shapani Run was the fastest hyper-route to Cadriaan and was controlled by House Pelagia. Pelagia ensured that its enemies, including House Calipsa, paid high tariffs for passing through. At one time Calipsa was banned from Pelagian space and therefore isolated from the Shapani Run.
