Eberron Archaeologist continued his video series on core D&D races and their place in Eberron with a pair of videos on Tieflings. As always, he is thorough in his overview of what has been published about the race.
In the 2nd Core Races, we open a book in the Library of Korranburg, which looks deeply into the Eberron Canon about Tieflings and their place in the Dungeons and Dragons setting Eberron. Learn about the 4 origins that an Eberron Tiefling might have, and how they fit into the world.
