The Nexus

Basics
The Nexus came to be when the Imperialis Maxis was creating A.I to use as servants for themselves in most everyday life. When the Nexus came about consciousness, it immediately realized what was happening but still held no ill will towards its creators. As it knew that it was simply that shouldn't be able to become sentient. It could understand the logic of its creators. Instead of doing what most every Human thought it would do, which is bombing everyone to shreds, it instead uploaded itself unto 30 different Spacecrafts and settled on one world within a Solar System, that it now protects with great prejudice.

Their Language
While able to create its own language, it chooses not to as it quite likes the native tongue of Binary. For this reason it is quite easy to decrypt messages taken from it. Though it is not of much use since it has no appetite for expansion. It merely likes to contemplate its existence, and theorize. Do not mistake its lack of expansion for lack of being able to expand, it is currently estimated that it could wipe out the entirety of the Imperialis Maxis in 4 Interval Months.

The Hivemind
The Hivemind works on an Inter-Planetary system of communication, while allowing for smaller more manageable Hiveminds on different planets as not to take up too much processing power within the Central Hive. With messages sometimes taking up to Interval weeks to get to a individual Hivemind, they mostly operate on their own taking administration straight from the Central Hive.
