[quote]Name all known Precursors including Gravemind.[/quote] The exact nature of the relationship between the Flood, particularly Graveminds, and the Precursors isn't known. But to answer your question, we [i]may[/i] have some names for Precursors in ancient human legends which pop up in Primordium. Mongoose, the Story Devils, Shalimanda, Mud, Tree, River, Rock, Cloud, Sun, Vaeites, and Alben are deities who appear in human legends, which revolve around stories of creation and insects who live in the sky. It's really interesting to consider the implications that we might actually know a bit more about the Precursors through ancient human tales than we think we do, but we don't know any of this for sure.
