A river? That is the biggest river of salt I've ever seen that it easily classified as a Sea, or Ocean of salt. Eldar being the lowest population in the game had everything hurled at them (including the kitchen sink) in mindless rage for things that were 99% not their fault (except the vehicle exploiters, they deserve to burn) and if your a main Eldar player that survived those times and is still here, hats off to ya.
No idea... Though I admit that some of the things discussed here make me ashamed of being a straight male. Seriously...
