The last hope for a dying empire
This story technically isn't finished yet as I intend on adding one more major story branch to it in the future. However, the story in its current form is complete and you should find no loose endings. There are also 8 separate epilogues to achieve.
This story can be very long assuming you're not dying. Years pass and your surroundings will most likely change. You may very well live a life time in the story.
As with any of my writings, the story comes before the game. However while there isn't a complex inventory and all of that you can technically win by getting one of the special endings. (You'll know if you get one because you'll get an epilogue)
There are also several points in the story where there are links that lead to more background information on various people, places, things and events. While not completely necessary to understanding the story, they do give you more insight into it.
