The Goliath

you parked your ship on the top of the megastructure, and you break in using a pretty old crowbar, ironically there was a slightly wedged plate. you are searching for the megastructure's core, which will probably take quite a long time. you can also take other things of value

a megastructure called the goliath thats 40 times the size of earth, the megastructure is on a planet trillions of lightyears away from earth, the planet, Kendarva, is over 800 times the size of the earth. the goliath has been long abandoned, but it is sentient, same with the other megastructures, it can speak with other megastructures using soundwaves that bounce off giant radio towers, there are 8 other megastructures, the warhead, the megaearth, the goliath V2 (a much bigger and more advanced version of the goliath, hence why it got abandoned) the K-457, the A-206, the koncord, the eradicator, and the overhead. each serves its own purpose, the original goliath was meant as a giant city, but the government wanted something bigger, so the goliath V2 was built, the goliath V2 is about 55 times bigger than earth. the warhead and eradicators are weapons of war, they are 10 times bigger than earth, but are super powerful, the overhead is used as a space station, its, of course, in space, the koncord is a supply megastructure, basically a warehouse, its the biggest out of them, 100 times larger than earth, and the A-206 and K-457 are used as bases for the military, both are 20 times bigger than earth. every megastructure is sentient, each also have different types of cores, the red cores are for megastructures that are 40 earths and above big, and the green cores are used for 39 and below. they also cannot talk to humans, only other megastructures
