Eight of the largest specimens known to man all once resided in this very location. Of course, they all occupied different spans of time, though many of them overlapped by a good several decades. The overlap periods are usually favorable, though sometimes two beasts of such stature end up doing nothing but fighting over the small patch of territory. It’s not exactly their domain because they don’t own it, but it’s a kind of sanctuary where they may do as they wish to their environment. They are highly evolved, sure, but their evolutions veered away from our human ancestors a couple million years ago when they decided to breed primarily for strength. At the time it was a brilliant decision, because they were quite fertile and stable. No other animals or tribes of humanoids would dare to invade a Megapithicus lair. Of course, they don’t call themselves Megapithicus. Our preeminent primate scholars assigned that fun name to them when they first saw the ulna of a particularly large Megapithicus man which they later dated to 20,000 BCE.
