They had all kinds of D and D lore draw from this this the best that the films could come up with? Ive seen the first two films and found both to be of poor quality.
The best D ad D stuff I've ever seen with the animated tv series they did back in the mid 1980's.
That's the one where the kids from our world go on a fair ride or something and get thrown into another world, with the little grey haired dungeon master? Aye, used to love it!
The Dragon Age series of games are heavily inspired by Dungeons and Dragons, but are not official D&D (Bioware saving on licence fees) - IIRC, Neverwinter Nights 1 & 2 which are official D&D games (i think set in the "Forgotten Realms" D&D Universe/rules were made by some Company, possibly called Obsidian, and the games, whilst the Plot, and so on was interesting and really good, the game had all sorts of technical issues, poor coding being behind it. And eventually, with the first game at least, the publisher brought in Bioware (the makers of Dragon Age & Mass Effect) to patch the game and get it fit for purpose - this is why there was a lot of confusion, and many people not understanding that Bioware came in after the game was built, and got it working, were blaming Bioware for the games problems on release.
There is an animated film set in the Dragon Age universe - Dawn of the Seeker which is pretty decent and a fun D&D style movie. It introduces Cassandra Pendaghast, a character who appears in cutscenes in the 2nd game, Dragon Age 2, and is a major character/Companion to you in DA 3: Inquisition. In Thedas, for various reasons, Mages are distrusted, and at the behest of the "Chantry of Light" Mages are kept in "Circles", magic academies if you like, where they are watched over, and if necessary "terminated" by the Templar Knights, who are the armed militia of the Chantry - they daily ingest Lyrium, a substance that in mages boosts mana/magic ability and allows objects to be enchanted, when taken regularly by a non Mage, such as a Templar, it gives them the power to dispell/suppress the magic of a Mage, making the Templar's perfect anti Mage weapons. Mage's who have escaped the Circle's notice, or who have escaped are known as Apostates, and the Templar's hunt them. If a mage is not careful, they can be posessed by Demons and become Abominations.
The Seekers of Truth are the people who watch the Templar's for Corruption, The Seekers are the people who formed the First Inquisition, after the Tevinter Imperium, which had occupied most of the continent of Thedas collapsed, and Thedas fell into chaos.
The Inquisition was not like what we had in the real world - in the lore of the games/movie many people believe, wrongly that the First Inquisition was like the one europe suffered, bloody, nasty, full of heretics being tortured and executed, but that is not true.
The Seekers administered Justice evenly, whether the suspect was human, elf, dwarf, poor, rich, a Lord of a Peasant, whether they were a Mage or not, they would convene a fair Trial, it's the fact that they were even and fair to everyone, and did not pick on a particular race, or the Mages that got them the bad reputation from disgruntled Lords, Racists and so on.
The Seekers brought Order and Justice back to Thedas at a time when both were sorely lacking, and thousands of Demons roamed the countryside. They then took down their banner and gave their support to Andraste's Chantry of Light when it was founded.
