I don't recall all the details.

He was corrupted by fighting off voidsent to protect the two Allagan clones inside the Void. As the WoL, that one Miqo'te and Nero were attempting to escape, Nero was weakened by the corruption and bid the WoL and Miqo'te dude to escape without him. As he attempted to move towards the portal, he was purified, presumably by the two Allagan clones nullifying the Allagan contract with the Cloud of Darkness. Thus strengthened, he made it to the portal and escaped, though not without some timely assistance from Cid nan Garlond who pulled him through it just as it was about to close.

As his plans were dashed by the sealing of the Crystal Tower by Miqo'te dude, he buggered off to go find other technology that might help him gain renown. Presumably his efforts eventually led him to Omega.


The Carteneau Flats are located along the border of Thanalan and Mor Dhona. It is not a location one can travel to in ARR outside of PvP Frontline matches (Borderland Ruins (Secure)). I don't believe it was an accessible location in 1.0 either outside of when they were shutting down the servers.
