Actually this is where my main info came from.
https://dragonlance.fandom.com/wiki/Teusten
It has also a description under Magic and Mysticism that explains Vlad Drakov's distaste for magic but his belief that magical equipment are acceptable for battle and why battling Azalin the wizard king of Darkon may not just be because of the domains size but because of Azalin's arcane abilities.
Magic and Mysticism
Magic of any sort is not often practiced in Teusten, but the people love to get their hands on magical items and use them to create their own tales of glory. To many in Teusten, an enemy with magic makes them all the grander and makes the story of a sword or axe wielding Teusten slaughtering them all the more grandiose. As such, most Teustens will not learn magic simply because a wizard defeating a powerful wizard is not as glorious as a fighter defeating a powerful wizard. Still, if that fighter ended up getting his hands on a magic weapon prior to defeating the powerful wizard, the story still is considered epic, and thus the use of magic items is “accepted.”
The following may also explain the absence of an official state supported religion in Falkovnia.
The issue of divine magic is different. In earlier years, clerics used healing magic and other battle-ready spells in Teusten just as often as an wizard in other lands, but that changed after the Starfall (Cataclysm). According to the Vroevadle, their gods never left. A test had been put forth to see who was truly faithful. In those times, clerics of the Vroevadle had faith in the gods for the sake of faith, and not for the bribery of magic spells. After the return of the gods, the clerics of the Vroevadle gained the ability to cast spells again, but many of them refuse this temptation saying that they are clerics for the purpose of praising the gods, not to become a holy-wizard. As such, divine magic in Teusten is a great rarity even though most of their clerics are capable of casting.
And something extra on demihuman slavery that can be used for Falkovnia.
Slavery is an acceptable part of life in Teusten. Although most dwarves are killed on sight, there are still several kept for labor. The same is true for minotaurs, humans, or elves. Elves are often seen as a weak race, and the Corinesti are believed to not deserve the sea, above or below. Those elves who prove themselves in physical labor are bragged about by their owners as “the best of their race.” Minotaurs are highly prized and respected by the Teusten. They are seen as greater fighters, and many people long for the peace between Teusten and Sakkaras to end so a great battle of strength can begin once again between them.
Thus Calibans may also be prized as slaves for their strength but not respected.
The info we have on Vlad Drakov from his time in Dragonlance is the following
Drakov hails from the kingdom of Thenol, which lies in the realm of Taladas on the planet of Krynn. In Thenol, Drakov headed a mercenary band known as "Talonsof the Hawk". His nickname was "the Hawk", and his men werecalled "Talons". He was noted for his ruthless and brutal tactics. He worked for whomever paid him the most money, usually the evil fanaticsof Hith.
On the
Adlatum Sourcebook it mentions under the description
Adventurers.
Many Teustens seek adventure in the northwest, anywhere from Blight Bay to the Broken Lands,but may be seen as far south as the Iron Isles. A brave few risk exploring the world further away, but stories are told of heroes who’ve sailed off the map to the west, daring to find the dark lands only the Corinesti are said to go. When adventuring most Teustens are in groups comprised of their own kind, but sometimes a slave of another race, or a kunda may be brought along as well to aggrandize their heroics into legends if they do not feel like exaggerating things on their own. It is almost unheard of to see a Teusten in a well-rounded group of adventurers comprised of an assortment of races.
Vlad Drakov may have been the descendant of Teustener explorers who ended up in Taladas bringing with them their aggressive culture and raising him under those standards.
