Why does a game have to tell you these things are bad? One of the things I always like about TES is that it gives you pages and pages of lore, biased lore, contradictory lore, and then lets you decide for yourself.

You could read several accounts of the Atmoran-Falmer war and still not have anything close to the real events. History becomes distorted rewritten, reinterpreted, or outright fabricated in the world of The Elder Scrolls.

Morrowind portrays slavery as a fact of life. Morrowind has slaves, it has slaveholders and it has abolitionists and liberators. You learn that slavery is held in Morrowind as a right granted by the Empire due to their agreement with the Tribunal, the Living Gods. You can even dabble in some slavery yourself if you choose to do so. My last character was a heavy abolitionist and killed many slavers and freed many slaves. Even my Redoran Stronghold was home to some freed slaves that I protected.
