OR humanity could have risen up yada yada. And war is waged...BUT Chaos pull a fast one while both are distracted. Then humanity/eldar are forced to fight the same enemy. Or they both get smashed in the surprise attack/fall(?) and the remnants are forced to work together. The Tau could join in later. Xenophobia could be gone and technology could actually advance...Yay! fanaticism might not exist! (hated all that crap)
