On his home world (not one listed in phase one), LonaLona is regarded by what passes there for civilised society as a dirty, disease-ridden savage. No amount of education will change that.
Elsewhere in the Fifty Worlds, LonaLona is respected as a courageous and shrewd warrior/mage.
On his home world, LonaLona's faith in his tribal deities, Father Sun, Father Rain and Mother Earth, is regarded as a pathetic and outdated superstition.
Elsewhere in the Fifty Worlds, people accept that a Sun God is a Sun God, regardless of the name you give Him, and LonaLona's refusal to give his Sun God a personal name is probably more sensible than many priests' insistence that you refer to the Sun God by the same name as they do.
Leaving the prejudices of his home world behind, LonaLona travelled to Megalopolis, first to study advanced fighting techniques, and then, when he discovered that he had an aptitude for it, to study magic at the College of Knowledge.
Despite their alignment differences, LonaLona and his one-time teacher Quentin remain friends.
[AD&D-Specific] LonaLona, human male, Str 16 Dex 12 Con 13 Int 17 Wis 16 Cha 12 Align N Hp 91. Age: Early fifties. Dual-Classed Fighter, level 12; Mage, level 28.
LonaLona's range of spells is very limited. He can cast spells from all schools except Greater Divination and Necromancy, but he does not know all that many spells. He spends so much of his time adventuring that he has little time left for updating his spell book.
It is possible that LonaLona has a latent psionic wild talent which he has not had time to develop.
LonaLona likes to dress well, but he is not interested in following fashion. To people who do not know him, he appears to be a prosperous and slightly old-fashioned middle-aged man, possibly a merchant or possibly a sage. The first clue that he is not what he seems might be when he refers to his well-kept town house in Megalopolis as "my mud hut".
LonaLona is there to remind player characters not to think in stereotypes. When you think of a barbarian warrior, you think of a muscle-bound moron, not someone intelligent, urbane and civilised. And certainly not someone who is liked and respected by academic magicians.
If, as might happen, the College of Knowledge needs the services of an adventurer who is not connected in any way with the Megalopolitan Knights, it is probably LonaLona whom they will ask.
As an active adventurer, LonaLona can turn up anywhere, but is most likely to turn up in the Megalopolis area.
