SCP Foundation

At the moment, my SCP is a large spere made of organic material that can withstand high temperatures. There is a hole to the inside which containts a large human heart being held up by multiple arms and legs. Inside the heart is an extremely hot liquid that is slowly pumped out of the heart and onto the ground causing the need of waste removal.

To add on to this i'd like to make the SCP itself hinted as being part of a whole. Perhaps something like a fiery titan or an organic spaceship, the heart being the thing that powers those things.

Sounds like a low-key version of SCP-058 (Heart of Darkness), and the "piece of something being part of a bigger powerful whole" is part of the premise of The Broken God.

Are you familiar with either of these works?
