Though no physical remains have ever been discovered, the existence of ents was recorded in what little has been deciphered from precursor historical artifacts. They appear to have been a race of sentient tree-like creatures which appeared just after the warpstone impact event, quickly building a small civilisation based in biotechnology and psyonics, with no use of metalworking or other more "conventional" technologies. They were perfectly capable of residing in Oceanyka's post-impact hellscape; in fact, they could not exit this region and colonise the rest of the planet, due to it being their one and only natural habitat. Responding quite reasonably to an "alien invasion", ents directed a total war effort against the crash-landed precursor, throwing every possible genetically engineered nightmare at them for decades. Precursors, under constant siege from the environment and under constant assault from entborn nightmares, ultimately seemed to have detonated a significant number of warpstone fusion bombs onto the entirety of Australia, destroying both civilisations and much of Oceanyka's flora and fauna.
