Mark Meer, the voice actor who played not only BroShep but also a bunch of aliens in the Mass Effect trilogy, has a side gig as a Keeper of Arcane Lore. That doesn't mean you should knock on his door next time you're in the market for a dark ritual to summon Yog-Sothoth—it means he runs a mean game of Call of Cthulhu.
The tabletop RPG based on the works of H. P. Lovecraft and the Cthulhu Mythos authors who followed him, Call of Cthulhu calls its game masters Keepers because it sounds cooler than "Dungeon Master." Meer acts as the Keeper for two highly polished actual-play series on the Call of Cthulhu publisher's YouTube channel, Bookshops of Arkham and Graveyards of Arkham. What marks them out from most other actual-play shows is that where normally the game master plays everyone else in the world, in these two series Meer has some assistance—guest actors who portray some of the more important NPCs.
