After seeing Dyson Logo’s beautiful little map of Onyx Hill, I decided to have a crack at drawing what lies beneath the hill. I’m planning to add this into my son’s game. I don’t think he’s going to find this site before we get to the location in game.

I figured the base of the onyx pillar would get bigger as it goes down. Perhaps there are some long lost inscriptions on the pillar in the depths. I’ve also added a small hidden nook at the very base.

The trick to getting down to level three is that you actually need to go down the pit trap in front of the altar on level two.
