Krister Sundelin is part of the Helmgast team, and the author of the acclaimed roleplaying game The Troubleshooters and the Swedish roleplaying games Järn and Hjältarnas Tid. He has produced roleplaying games for the Swedish market since the mid-1990s as a freelancer, self-publishing and as part of Helmgast. Being in his 50s, he has been a roleplayer since 1982. His bookshelves are filled with more roleplaying games than he will ever play, and the attic is also full of them – all for reference, of course. When not making roleplaying games, Krister works as an e-learning producer for the finance industry. It is exactly as interesting as it sounds.
