I have just finished reading Halo:Primordium, and the book was a terrific read. It answered a lot of questions for me, but it also raised some for me. The Captive was a little confusing for me because in the book it said it was made of dead bodies like a gravemind. The Captive also said that the reason the flood was used to bring unity to a race of species.
My first question is: What are the precursors? Are they a special type of flood, or there just normal graveminds, or something else? My second question is what is the purpose of the flood and is there a cure for it?
Please leave answers below, it would really help.
