Written up ~1200 words for premise and statblocks for #KnightcoreTheRPG for a New Year's Eve one-shot. Where in some RPGs statblocks are full of, well, stats, often rarely used, in Knightcore they are the barest of stats, but full of story, loot, and world-affecting options. #knightcore #ttrpg

Knightcore the RPG. Chivalry meets fashion. Swords meet myth. The world is dark and chaotic but you are the shining beacons of hope within it. mottokrosh.com/knightcore. A bespoke yet familiar system.

@josephrlewis.bsky.social @themerrymushmen.bsky.social I’m coming up to probably the final session of Raiding the Obsidian Keep, but one thing confuses me: The chanting priests in Avito’s room - why don’t they enter the private sanctum and complete the ritual themselves?

@josephrlewis.bsky.social Hey Joseph. So I’m currently running your excellent Raiding the Obsidian Keep to play test my Wolden RPG with “classic” OSR adventures, and the party rescued and nursed back to health Patnuvia, the ancient vampire from the “orbital vampire city of Araveshti”. 1/2

Map of the venue in the style of an old dungeon map. The Mottokrosh Machinations stall, with many books on display, and Karen smiling at the back. Frank GMing at a table with five players, two men, three women, lost in the books and story. A shot of the RPG room at Tales Untold with Kara as GM gesticulating, and many players and audience members watching and smiling.

October 11th is the 2nd Berlin International Roleplaying-game Convention (BIRCON)! I'm one of the organizers, and In the run-up to the con we're doing a series of (hopefully) useful livestreams on our YouTube channel. The next one is on Friday 19th at 18:00 CEST.
Fun with Strangers - Tips for playing at cons, with Rebecca, Frank, and Kara. The background is a whimsical illustration of the BIRCON bear running a cosmic horror game, surrounded by scared anthropomorphic animal players.

Wolden Issue 1 was successfully kickstarted earlier in the year. Work on issues 2 & 3 has been continuing steadily. Here are the covers for all 3 (subject to change).

Art for 1 and 2 by Henriette Bold, and 3 by Alyssa Avery.

Young witch mid-ritual, with crucified captive. Frazetta style illustration of extra tall, muscular sorcerer-king with long hair draped across throne, with his favorite concubine by his side. Both clad in golden, flowing fabrics. Comic style illustration of a Regency man and woman in front of a banquet. Odd things: the man wears a meat cleaver, the woman is missing an arm, the table has human meat on it.

With more games and exhibitors than ever before! Which, since it’s the second year, is more of a default expectation than a glorious highlight. But still.

Who's writing up the next cults for Wolden? This guy! The Lion Sodality is a group of "Regency" gourmands and adventurers. A bit like Pride and Prejudice and Zombies, but also for taboo foodies. With an awesome art piece by Alysa Avery.
