What I was seeing was that the mutated orcs were stepping into the array that was releasing the corruption energy.
These mutated orcs were standing in the spots that the cloaked shaman had shown me before. These were the spots of the array where the sacrifices should be placed before they were taken by the array.
After standing in those spots for a bit, there was something that made the mutated orcs disappear without a trace. It was as if their bodies were sucked up by something and turned into pure energy that was absorbed by the array.
Once that happened, it seemed like more corruption energy came out of the array.
So the transfer of corruption energy was done through the sacrifice that was done with the array.
It was no wonder the corruption energy monsters just stood on the side and watched.
