Worf’s brother, Nikolai Rozhenko, returns to the spotlight amidst a deadly revolution on a Klingon frontier world. Supplementing its monthly Star Trek: The Next Generation title, DC Comics published a variety of miniseries offering special tales with a larger scope. Among these was Shadowheart, a four-part storyline penned by Michael Jan Friedman. Illustrated by Steve Erwin and Charles Barnett III, Shadowheart centred around Lisarion, a Klingon colony world under revolt- and the last known home of Nikolai, Worf's human foster-brother, introduced in the episode "Homeward".
