Having played Dungeons and Dragons (D&D) 3.5 edition in college, when I got an actual job in 2008 and was able to afford things I started playing RPGs again. Unfortunately, I ended up playing a lot of D&D 4th edition, but at the time I was loving it. After getting the core books, I wanted to get some of the vast sourcebooks that were available. There were a ton of different settings, but the one that grabbed me was Eberron. Written by Keith Baker, it was a custom setting that was submitted to Wizards in a D&D3.5 contest that became a full setting supported in 4th edition as well.

If the idea of flying ships, magical trains powered by elementals, and huge steampunk colossi in your D&D game sounds awesome to you as it did to me, then you are in luck. Wizards of the Coast has teamed up with Keith Baker to make Eberron: Rising From The Last War, an official D&D 5th edition sourcebook that updates the lore of the world and brings its mechanical and mystical creatures into the most recent version of the game.
