During the New Sith Wars, The Black Sun, worried about their business goes about investing large resources into a project they dubbed Harbinger; to act as the safe guard against the Jedi, Sith and other syndicates that would be intent on removing them from power, if the opportunity shows itself. As such they created a one of kind killing machine, made up of some of the most dangerous races in the known galaxy. But due to unknown sabotage their plans are ruined and their organisation set back centuries in the many plans. Follow this entity on it's journey through the galaxy, as it stumbles upon one mess after another and tries to find its purpose in this vast galaxy.   This is my own little star wars fantasy and wish fulfilment so don't come expecting overly complex plots and fully fleshed out galaxy. Hopefully I will be able to make this fun. Also I won't be decribing the species often, so you're going to have to look them up yourself. There are just too many to constantly be describing them beyond their garb.
