Precursor (Halo)

not much is known about the precursors. the only proven fact about them is that they where the dominate species before the forerunners. all other information is based on gossip and statements from UNSC marines and covenent sepratists. it is tought that there demise is from a similar disaster witch destroyed the forerunners, a group of marines on the ark claim they found a terminal with a translator with information about some type of epidemic in the era of the precursors. the marines also claimed it was a type of germ, unlike the flood, witch is tought to be the reason the forerunners treated the flood like a disease. another statement from a group of eliets says that the precursors had a similar relationship to the primitive forerunners that the evolved forerunners had to humans. there is more known information known about them but most of it are things such as, for example, the name of a precursor store chain. they where tought to have similar anotamy and size to humans, but look like a cross between eleits and jackles. there culture was tought to be similar to that of the forerunners, but less peaceful and they'r technolagy was slightly more advanced than humans.
