Michael O'Brien is Vice President for Chaosium. His role encompasses creative development, community engagement, licensing and MGF. Better known in the gaming community as “MOB”, he has been a long-time creative force for RuneQuest and Glorantha. As well as being a contributor to the critically acclaimed Guide to Glorantha, his professional writing and editorial credits extend back to the early 1990s when he was associate editor of the Glorantha magazine Tales of the Reaching Moon. The 1992 RuneQuest release Sun County, which he wrote working with editor Ken "The Rune Czar" Rolston, kicked off what became known as the "RQ Renaissance".
In mid-2014 MOB returned to Australia after a decade in the Middle East, where a senior leadership role in higher education took him to places as far afield as the United Arab Emirates, Sultanate of Oman, Qatar, India and Somalia. He is now based in his home town of Melbourne.
MOB is a member of Chaosium's Board of Directors.
