Special Containment Procedures: Satellite video must be transmitted at all times. Any satellite shutdown should be reported to head researcher Dr.██████ at the site 19 interstellar sector. Broken satellites are to be repaired via long distance drone to repair images.
Description: SCP-4155 is a large membrane style substance located in the center of the andromeda galaxy with apparent magnitude of 2.3, and a actual magnitude of . It's estimated size at the moment is 80-90 meters in height.
The item itself has multiple black chain looking objects wrapped around it. Over time since its discovery, these chains have been bleached in color from the intense amount of light around them.
An item inside, SCP-4155-1, is a 90-100 meter tall dragonesque creature,similar to a wyvern. The creature is most likely a quadruped. The creature is thought to have been dormant for thousand of years, until its discovery in ██████, by Dr.██████.
The body itself seems to be made of a glowing substance similar to glass, but extremely harder.
All attempts destroy SCP-4155 and SCP-4155-1 with ICBMs have gave no results
Addendum SCP-4155-A: Recently, SCP-4155-1 has broken through many of the natural chains around him with its wings. This has caused fear among staff as we are not sure what SCP-4155-1 is capable of and I wish to say this. From what we know and what we can do we can not contain SCP-4155-1, we can only observe what some of the researchers call its "growth". Though for now we need to advise in a event of its "hatching" to listen on channel ███ of the radio intercom for updates. That's all we can say
