Let it be known that the eastern section of the Venomweald is thoroughly under Ommok's grip as part of his ogre kingdom. There might be rogue bands of ogres or small ogre hideouts in other sections of the Venomweald as well, though the ogres mostly keep to wild hills around the jungle and only ever go into the very outskirts. Even they are scared shitless of what is actually inside the jungle, which should tell you something about the futility of putting an actual civilization in there.

Rtron has mentioned plans to add some ogre-like beings called Grotlings to other parts of the Venomweald, so they'll eventually be there to contest control of the area. And from what I recall, I suspect that they'll be even more scary than ogres.

Also, I've already canonized the presence of several Hain villages in that grasslands south of the eastern Venomweald by the river; Ommok encountered them a while back in the post where he went on a long trip across half the world to find his magical stone. Without spoiling much, I have plans for Ommok to return to those Hain villages again.
