Tales From My D&D Campaign Wiki

MN-8 was a Warforged menial labourer who was part of a four-Warforged team who oversaw the Northern Terminus along with some Worker constructs.

In the aftermath of the Ytarran extinction, he and his colleagues began to break down due to lack of repair and he eventually died of "old age", along with CC-1. TR-4 and AB-21 eventually cannibalised them to prolong their own lives.
