Fragmentation's detrimental effect is by opinion, Treewyrm. What the hell are the Blood Dragons? What the hell are the Bundschuh? Groups that have outcasted themselves from their original family. In this case, the group may be outcasted against their will, but it's all the same.
It comes down to whether or not you want to contend with another RP, sadly. In my eyes, conflict brings greater opportunity for RP situations. In yours, it may just frak everything up.
In the end, you rule the Keepers, and you decide. I just wish we could open our minds and work things out, instead of letting our opinions reign supreme.
