DOOM: The Dark Ages - The World Spear

For a brief period of time there was an idea of visiting the world spear in the Dark Ages. What would that have been like? The view here was from inside the chasm created by its ancient impact and what sort of biome would have grown around it. Also tubular space-station
like vibes.

To simplify things, I imagined at the time that the actual gameplay space would take place on and around a castle on the back of a walking creature. Maybe that is more complex then it needs to be but it would keep the player isolated in one location so the 'world' could mostly be represented in Skybox form.
