Like it or not, Star Wars: the Old Republic is not so dissimilar from its source materials -- its planets universally have themes. There's the city planet, of course, and we all know there's going to be the desert planet. And, as it stands, we're now poised to have the weapons planet -- which promises to be as explosive as such a title would suggest. The game has recently unveiled Balmorra, the site of an ongoing struggle between the Republic and the Sith Empire, where the victor claims the preeminent weapons manufacturer in the Core Worlds. The planet started as an ally of the Republic, but during the long war with the Sith Empire the Republic was forced to scale back its efforts to help perserve the planet's independence, culminating in a full withdrawal of its reinforcements to the world.
The Sith quickly claimed the planet in force, with only an underground resistance left with some Republic support to fight back against the invaders and do what damage was possible. Of course, when you're on the most deadly weapon-making planet in the area, you can do quite a bit of damage. The rejuvenated Republic is now returning its troop presence to the planet's surface in hopes that it can wrest the world back after the brief lull of peace, but the Balmorrans haven't exactly forgiven and forgotten the earlier abandonment. For more information on what promises to be one of the most explosive areas in Star Wars: the Old Republic, take a look at the official page containing more pictures and information.
