Hello! I’m Rosemary (R.M. Grant).
I am a passionate and dedicated game master, TTRPG designer, campaign planner, and worldbuilder. I have been running games unprofessionally since 2015, and have published several successful 5e homebrews in that time.
I am experienced in a variety of systems including but not limited to:
D&D (3.5 Edition, 4th Edition, 5th Edition, 5.5 Edition)
Pathfinder (1st Edition, 2nd Edition, Starfinder)
Forged in the Dark (Blades in the Dark, Scum and Villainy, Varsity 2)
Powered by the Apocalypse Systems (Apocalypse World, Monster of the Week, Dungeon World, Dungeon Bitches)
World of Darkness (Vampire the Masquerade 5th Edition, Werewolf the Apocalypse, Werewolf the Forsaken)
Mork Borg
In the same vein, I have run a wide variety of genres and concepts. From magical girls defending the world from invading aliens to
I have since worked as a professional GM starting in 2022, running over a hundred paid sessions during this time. I have developed complex worlds, managed character arcs, and run many a combat. In 2021, I released my first independent tabletop RPG, Varsity; in 2023, I released the second edition of the same game. Both have been well-received, and have spawned a number of podcasts, YouTube playthroughs, and even fan translations!
Now, I am offering my skills and experience to other GMs and game designers.
Committed to Never Using Artificial Intelligence!

Testimonials
“The best GM I've ever had - I can't imagine my characters in any other worldbuilding other than hers. She really knows how to make your characters have a place in their world and propel their storylines in the most unexpected but spectacular directions.”
— Ronan (Game Master Services)
“[Rosemary] has a lot of patience for new and old players alike, and makes sure shyer players (like myself) feel included and comfortable roleplaying. She was incredibly flexible with me in terms of pushing the boundaries of the system and standards with my character ideas, and has the homebrew chops to make any vision you have come to fruition.”
— Haley (Game Master Services)

Game Design Collaboration
Need help creating a killer dungeon, plotting NPCs, creating homebrews, gathering battle maps, or otherwise putting the finishing touches on a session that you want to run? Look no further. Our focus can be on whatever you wish in the sphere of TTRPGs, and for any system with which I am familiar.
If you have an idea for a tabletop roleplaying game that you would like to bring to reality, but want a professional’s eyes on the subject, this is the perfect service. Over the course of one or more calls or chat sessions, we can iterate on your ideas to refine a tabletop game, including everything from initial mechanics to final polishing read-throughs.
You reserve all rights and ownership of ideas and mechanics we create together!

Game Master Services
Are you a forever GM who wants the chance to play with a professional, or a beginner in search of a great onboarding experience? Choose a system, a group of players, and (optionally) a setting or campaign pitch, and I will get to work on your behalf — providing all of the necessary background planning so you can sit back and enjoy.
Sessions last 4 hours with a 10 minute break at the start of hour 3. For my first session with a new group or story idea, I always offer a free 30 minute to 1 hour “session 0” consultation.
