"Rodney"

"Rodney" is the name given to a huge, rod-like structure found outside of the known cosmos.

Basic Information
Rodney appears to be an extremely long cylinder ($$10^{2\times10^{10}}$$ LY long, 100 LY wide) that is gray in color. It gives off huge amounts of gamma rays but it is unknown what it's interior is. All expeditions sent to Rodney have recovered unknown artifacts from it's surface.

The material that makes up Rodney is some copper alloy with traces of second Realm material such as Yetmmud Residue.

Rodney seems to be completely invisible to the naked eye, and can only be seen with special equipment.

Expeditions
Many expeditions have been sent to Rodney. All have uncovered strange objects and gotten valuable information.

First Expedition
The first expedition sent to Rodney was in 1034 OYC. It was conducted by a few extremely powerful civilizations in The Far. There, they found precisely 13 anomalous objects and also discovered Rodney's peculiar habit of attracting Glitchonicite and Sentient Substance like a magnet to magnetised iron.

Second Expedition
The second expedition launched in 2305 OYC was a disaster. The creatures involved in the expedition tried to break inside Rodney. They successfully drilled a hole straight through the thin copper outside. When they got inside of Rodney, some kind of gas came out, melting all materials around it (except for Rodney itself). Only one creature lived to tell the tale, and it was seriously damaged, both mentally and physically. No artifacts were recovered during this expedition.

Third Expedition
The third expedition (in 6504 OYC) wasn't as catastrophic as the second one. This time, over 2806 individual artifacts were recovered. Almost all were brought to the Ontological Museum. The ones that weren't were lost when Rodney was accidentally punctured again, causing severe damage to the creatures' ship. They had to wait a few more weeks before they were rescued.

Fourth Expedition
This expedition is the most recent one, being launched in 8948 OYC. A mysterious radio wave was detected from Rodney's surface. The radio wave seemed to be coming from the inside. Other than that, 370 separate artifacts were found. None of the gas leaked out again during this expedition.

Unknown Artifacts
There have been many artifacts found on Rodney's surface. These objects are completely alien and no creature has yet figured out how they work.

Here are some notable objects:
