• It was originally named Haulteclaire.

Description (Astrography & Planetology)

Mjolnir orbits a much larger rocky body named Niflheim. Niflhiem is a massive world shrouded in clouds. Automatic probes and most manned expeditions all fail to return from voyages into the atmosphere so little is known about the world.

Mjolnir has two stars in the star system.

History & Background (Dossier)

The planet's major resource is its vast oil pools, and mining of these pools is Mjolnir's primary industry. A devastating earthquake on 126-1044 destroyed Mjolnir's capital, Midhvolf, and reduced the planet's population by 75%. Midhvolf has not been rebuilt, and the new capital has been established at Uttonat Omrade. Mjolnir's starport is Armundshaven, which is also the world's commercial center.

Mjolnir was originally named Haulteclaire, and has been largely overlooked and under-populated throughout the history of the Sword Worlds.
