"The Open Gameplaying Licence 2.0"

"The Open Gameplaying Licence 2.0" for Ars Magica 5th Edition. 2-6 players, could stretch to 8. Pre-rolled characters available, or bring your own (must be magi). Suitable for all, from beginners to seasoned pros, but will need at least one seasoned pro in the troupe. August 2023. Gaming mega-corporation Witches By The Seaside recently unveiled the 5th edition of their classic Caverns & Griffins roleplaying game, together with a revision of their Open Gameplaying Licence. Unfortunately C&G 5th Edition seems to incorporate real Hermetic spells, and mundane players are somehow able to actually cast them. Magi are asked to assist Interpol in investigating and solving this problem.

If you bring your own existing magi character, you may assume some truly stupendous longevity ritual or other similar wibbly-wobbly timey-wimey hand-waving, to permit your character to play in the present day.
