We are not tolerate any sides and we hate both side in the same way. The Alliance with the Ashlan Crusade is totally based on "we take advantage of each other". This is well known, planned thing with the AC staff. <3
We are smaller than the large factions, they are too (ICly) and alone we cannot fight against the Maw, this is why we made the alliance with them. And the Sith, ICly we never liked them, but again we needed them against the Bryn'adul (Civil war). And the war against the Sith was completely IC again, thanks to the EE/AC/Kainate junction where Carnifex tried to kill Ingrid.
And in plot wise, if you are with the good guys, no one ever consider you're intention the opposite (in this case to destroy the Force, espeically if you were able to convince the most relgisious group on the map) and while no one watching you ICly, you can do your own stuff in secret.
The EE-AC was entirely IC... we started to play yes we had our plans OOC, but if our players wouldn't have had a good time with each other during the game and ICly the things wouldn't have turned out the way like they did, we wouldn't have forced this OOC then and there would have been no alliance, the entire plot and games happened IC, we built the EE/AC thing ICly.
And yes, we are allies with a light side group, because of the narrative.
