Gram Arm

An astrographical feature, a branch of the Spinward Main, located in the Sword Worlds Subsector of Spinward Marches Sector.

The Gram Arm is normally considered to run from Tizon to Tyrfing, although many attempt to include Beater and Sting.

Sword Worlder contact with the neighbouring Darrian Confederation comes mostly through Tizon, with levels of trade varying according to the political situation.

Hrunting is sometimes considered to be part of the Gram Arm and sometimes part of the Gungnir Spur.

History and Background

The Gram Arm contains the earliest worlds settled by what became the Sword Worlder culture. Expansion outward from Gram was driven to some extent by astrographical convenience. Careful reconnaissance and planning allowed a rapid early expansion that established some of the Sword Worlds as powers for the future -- but it was these emerging powers that ultimately derailed the development of the Sword Worlds as an interstellar power when they began asserting independence and pursuing their own agendas.
