Alister Azimuth could have been seen typing into the keyboards at the Obsidian Eye in Lumos. Considering these were written in Zoni, this must mean he knows how to write and speak Zoni. This is not unlikely, seeing as he spent many years of research into the Zoni - evident by his home in Volgram Pass. Also, Nefarious at the Mnemonic station Alpha, was trying to hack into Clank's brain. The buttons he was pressing in the station consisted of Zoni characters.
