Some time ago, on the 1st Floor of the Tower, shortly after opening the dimensional pathway to the Midnight World.
When the Midnight World was first connected to the Tower, the Orks from the Bloodtooth Tribe noticed the humans who came from a technological civilization, which was relatively advanced, captured them first and attempted to get from them as much information as possible.
After a series of brutal interrogations and torture, they managed to find the dimensional pathway which was connecting to the Midnight World; they immediately started the invasion of the new world.
For the Orks of the Bloodtooth Tribe, it was a glorious time, as they could finally unleash a Waaaggghhh on the unknowing enemy. Slaughter and pillage to their heart's content, kill anything that moves and wages war on their enemy in the glory of the Green Gods.
Such was the way of the greenskins.
