Iskellian Technology Solutions
There are many tech companies throughout the system, producing everything from computers to lasers, and Iskellian is the largest. Iskellian holds the Alliance contracts to produce arms, spacecraft, and weapons for their troops. The products it sells are the best money can buy, and what Iskellian charges for its wares more than makes that point. Given that the Alliance buys arms from Iskellian, the Alliance has laid down the law that none of these weapons can be sold to anyone else.
However, Iskellian does manufacture weapons for civilian use. These are not the same weapons that the military buys, of course, but they are of the same high quality and have the price tags to prove it. Such weapons are rarely seen on the outer worlds and few are on the black market. If you can get hold of an Iskellian weapon, you count yourself lucky.
