Some maps (e.g.
http://wiki.project1999.com/Thurgadin ,
http://www.steveprutz.com/eq/thurgadin.htm ) and ZAM (
http://everquest.allakhazam.com/db/npc.html?id=5958 ) suggest there were guild trainers inside thurgadin. Loremaster Borannin certainly isn't. There may be others.
Digging up era-appropriate evidence for this is left as an exercise for the reader.
