The Grand Nalaxian was a series of modified Nalorgian spawning pools, created by the Empire of 1,000,000 Suns shortly after the conquest of Artanis 4.  The Grand Nalaxian was based on several other such pools that had started to develop a sort of autonomy, and had influence over the Nalorgians of their regions, but the Grand Nalaxian was vastly more complex and had its own consciousness.

The Grand Nalaxian was intended as a planetary governor, a role which it served well, but it also transcended its original purpose and became a vast repository of knowledge.  One of its most notable achievements was the creation of the Nalaxian Code, an algorithm that could protect robots from the influence of Troniac, during the 1,000 Years War. 

A huge palace was built around the Grand Nalaxian after it was established on the largest continent of the Artanis system, and beings from across the Spozak gathered there to exchange knowledge and seek the advice of the Nalaxian.  Nalorgians entering the pools could directly exchange memories with the Grand Nalaxian, and it was home to the most elite of the symbiotes. 

During the War of the Empires, the most productive and intelligent sections of the Grand Nalaxian were secreted away by the imperial government, with help from the Yatagarasu, and eventually became part of the nascent Galactic Republic on the planet Tartarus.

The conscious existence of the Grand Nalaxian stretched from the early days of the E1MS until it joined the Galactic Consciousness, midway through Era-2, giving it the longest living memory in the recorded history of the galaxy, even longer than the famously long memories of the Gorox.
