Once a murder has happened, to go back in time and prevent it might seriously mess with the timeline, and that is where the Time Patrol's Murder Squad comes in. They try not to kill anybody themselves, except in emergency defence of themselves or the timeline, but they are known as the Murder Squad because they are there to make sure the murders of the past happen.

Here is the governing hierarchy of a standard western style modern military. This is mostly just an amalgamation of the military rankings used primarily within the US and UK armed forces with some inventions of my own. (For example, I gave the OF-10 to OF-7 Air Force ranks the title of 'Marshal' just to make them more distinct from their Naval and Army counterparts.) If you're wondering how I came up with this list, I used this link as a frame of reference: http://legacy.koveras.org/ranks/ranks.html

The heart of Humanity, the Starkin Federation is the largest faction of Man amongst the stars, the mightiest vehicle of his ambition.

The Sundar family name was one spoken with honor and reverence. None were ever spoke ill of, and should a question arise of their honor and integrity it was quickly set right by those who knew them. Now they are a fallen noble family of disgraced knights who are fearless, emotionless, and uncaring for anything other than own survival and vengence.

Charity out of spite, resistance in submission. Loosing everything can produce strange associations indeed.

If one travels, you might notice it. Each one has a blue orb on their signage or somewhere in the shop. The merchants seem to specialize in foreign goods, but often buy local produce and products, to trade in other places. They seem totally unrelated to the others. It seems to be a secret organization, but nobody knows for sure.

The Blades of the Golden Sun are an organization lost to history. They are a legendary group, with songs, stories, and histories written about the exploits of their members. They were warriors of the famous Sun Swords, fighting against 'The Evil', the Dark Night.
