Oh, O-App-Pesi is featured in the White Mage quests, it appears that he is busier than ever with his duty as a padjal that does not involves the Stillglade Fane.
It serves to remind some guilds were not so much guilds but other institutions offering training (Miner's guild was the Amajina & Sons, Archer's guild was the God's Quiver, Lancer's Guild was the Woodwailers), some had guildmaster shifts when the guilds became independant (even if, for say, the Miner's Guild is in a space rented from Amajina is pretty much has offer it's top miners to them to keep independant).

Lusavari has a good list, I think he's got it correct!
