"...Teranus returned to looking around the labs, getting a feel for how the place was set up. Quite a few pieces of machinery lay in the corridor, not out of accident or as a result of what had happened, but as if it was meant to be there. Teranus got the feel of an overcrowded hospital with the sometimes near-impossible to pass obstructions..."

This is the way I imagine the inside of the amalgamate contamination epicenter, a research center, looks like that is described in this story, written by Draconian-man

In the image is also pictured a larger form of amalgamate that has assimilated a former inhabitant, of the now mostly desolate colony, into itself.

I felt inspired to draw the amalgamate after reading the story and I suggest you give the story a try, it's a pretty good read!
