Rittermarch - #MoreMausritterMarch

Rittermarch, named after JRR Tolkien’s Riddermark. The Riddermark was the vast lands of the Riders of Rohan and comes from the Old English Riddena-mearc which translates “Territory of the Knights”

Rittermarch will be a community world building experiment where participants will create (either once a week or one for the month, their choice) a single hex, a Settlement, an Adventure Site or an actual guided Adventure. These can be filled with NPCs, factions, items or spells per the Core Rules of Mausritter. 

Participants should create and post on, here on this Official Jam Page and share to Twitter using the hashtag: #MoreMausritterMarch. At the end of the month, ManaRampMatt will compile all the sites into a large Hex Crawl titled “The Ritter’s March” This map will be keyed to all the individual submissions. 

At the end of the month, all submissions will be assigned a number and there will be a randomized set of prizes (more info to come).

This is meant to be a fun and creative experiment and there are already plans being made for the second installment of this Jam, MAYFIELD - #MoreMausritterMay
