Mmh. Last time I even bothered to check what happened outside my tower or my vault, I was kinda all those, plus I had integrated the Mages Guild with Telvanni. I'm also the chief of the Skaal, Champion of Bloodmoon Prophecies, Patriarch of the Temple slash He Who Slayed the Tribunal, Grandmaster of the Morag Tong who permanently defeated Dark Brotherhood, among other things. It's also Azura who is my favorite pet, and not the other way round. But actually... everything else but Telvanni has been some minor side fun at most. Also, the last time I checked, even the Mainland Telvanni are but a little side branch in my grasp at the moment. I don't care that much, though - I'm writing a systematic study about the essences of other realms at the moment, which will, hopefully, drive people like Rilvin and Divayth to make their puny little research reports even a little bit better. That study is the only thing I'm focusing in at the moment.
Ooh, titles?
Telvanni Salvor Dareleth, Archmagister of Great House Telvanni and Lord High Magus of the Telvanni Council, Lord Uvirith, Nerevar Reborn, Nerevarine and War Leader of the tribes Urshilaku, Ahemmusa, Erabenimsun and Zainab, Hortator of Houses Telvanni, Hlaalu, Redoran and Indoril, Arch-Mage of the Mages Guild (nominal, the guild has been eradicated), Master of the Fighters Guild, Grandmaster of the Morag Tong, Knight of Morrowind, Patriarch of the Tribunal Temple, Factor of the Solstheim branch of the East Empire Company, Master Thief of the Thieves Guild, Chieftain of Thirsk, Blodskaal of the Skaal. Etc. I'm sure I left some out.
