Elevator Pitch: So, a giant 3km high tower made out of a carbon monoxide solid isotope called ”Carbon-16”. This tower resides in an alternative dimension called XO-16 and is believed to be one of the superstructures created by an ancient race of humanoid entities in order to maintain/generate (by unknown means) reality. Like a beacon for existence. Because Carbon-16 is not very resilient, it is of high priority that Foundation’s MTFs protect it from receiving any damage.
It has been suggested that the SCP had a self-defence method to protect itself from incoming damage but unfortunately, this system has been destroyed or it’s malfunctioning (it's superheated) because of excessive attacks from extra-dimensional forces. It's now up to the Foundation to protect it until it can do it again.
Central Narrative: There are many extradimensional beings that try to destroy the tower. The Foundation thus constructed an outpost in this dimension to deal with all the enemy forces. Attacks to the Tower occur via huge waves of concentrated light or via direct projectiles or even with enemy forces coming in-person to attack the Tower. While the Tower actually regenerates over time, if it is damaged significantly, reality alterations will occur.
Hook/Attention-Grabber: The strange thing is that the isotope that makes up the Tower itself has some anomalous properties that can be used to create reality anchors, small devices used by the Foundation to negate the effects of a reality disrupting anomalies. While Carbon-16 can be created in a lab, it has been shown that only the on from the Tower itself possesses anomalous properties. Thus, protocol Hephaestus was born. Designed to collect Carbon-16 from the Tower.
The Tower was discovered in 2016, after some reality disturbencies occured on Earth any some nearby systems. The Foundations tracked the disturbances back to an alternate space, where they found this SCP. It is also to notice that there are possibly more then one Tower like this one in the Multiverse. None have been observed as of now.
Another thing, the beings that constructed it have died long ago but a few signs of their civilization remain as strange hieroglyphs and low humming sounds coming from the Tower itself.
Additional Notes: I really have more to say about this SCP. Thank you!
