Steel, Sturm, and Kitiara are in a series called the Dragonlance Chronicles.
Steel was conceived before Sturm was killed. However, my personal sentiment is that the series was ridiculously overcommercialized, they tried to add so many pre-stories and post-stories to the original 3 (or 6) that the quality of the plotline has become totally diluted. Keep in mind that Sturm also traveled to one of the moons in a hot-air ballon in a prequel story.
Steel Brightblade was conceived when Kitiara and Sturm traveled together five years prior to the War of the Lance. Steel was then born at a woman named Sara Dunstan's house outside Palanthas. Kitiara let Sara raise him and when Sturm died Sara and Steel moved into the city of Palanthas. It's better explained in Second Generation by Margaret Weis and Tracy Hickman. Oh and I don't think the series is over commercialized I think that they could have done more with the original characters and the new characters. I'm also looking forward to the movie when it comes out next Autumn.
