The Lumati are divded into two different parts like the Drack and the Minbari, but unlike the Minbari, it set at brith. The Lumati don't call them that they just call them Upper and Lower, the Upper one is more taller than the Lower one. Because of the this strick seperation of the two of them it has prounduced a symbiotic realoship behind the Lower and the Upper. This is when that Upper one talks through the Lower one while on mission to what called "non-suppior" races. They also know that alliances with other races are improant, but only do it with races that they called "Suppior". When a deel has been strick, no matter what the sex of the people invoule in it both of them will have sex. Werid isn't?
