Suffice to say, though, if I was writing the plug-in, the Gaitori would take one of three actions:
1) Refuse any alliance with the Humans and Ishimans.
2) Accept an alliance with intent to betray them.
3) Accept an alliance (but this is a strained, uneasy alliance at best for all parties concerned).
I predict that the Gaitori would be relatively divided on the subject. Heres my reasoning:
1. When the Cantharans threatened their wellbeing, the Gaitori sided with them. This leads me to believe that, in general, the Gaitori are somewhat cowardly. Since the Gaitori were only familar with fighing far away from their home systems, they didn't really buckle after losing a good portion of the territory along the border. However, if the Obish were to capture a few of the Gaitori planets back home, they'd start to worry. This leads me to believe that a large portion of the Gaitori would swap sides to save their hides.
2. Of course, a few Gaitori won't like the idea of betraying the former alliance and making a new one (recall the Gaitori Seperatists). So, these Gaitori would be willing to fight alongside the Salrilians and would prevent the human sympathizers from assisting the battle for Earth.
I hope that clarifies the Gaitori and Obish Campaigns. Now to clear up the others
