Mothership to Cairn conversion

I’m a big fan of not reinventing the wheel.

Has anyone written about converting from Mothership to Cairn? I’m reading the advice in the Warden’s Guide while hoping someone smarter than I has given this some thought.

Specifically, I’m looking at Desert Moon of Karth and Wages of Sin for a western inspired setting.

:waving_hand: I’ll be interested in what you end up doing here. I still havent decided yet whether I was hacking mothership with thematic backgrounds and less horror or converting the material to a new system like you propose.

I think the person to ask is bread wizard (user name on the usual suspects of osr discord servers). He posted that he had used Monolith (a cairn-like) to play desert moon of karth. He wrote about the experience here and might be willing to share his notes.

@bread_wizard is indeed here!

Yes, and I absolutely remembered that I had set up an account here!

Here are my rough and ready conversion notes for Desert Moon of Karth-- most of these I just cribbed from the Monolith bestiary, finding “similar enough” stat blocks for the basic stuff in the adventure. I also borrowed the “Stress Outcomes” from Liliputian to simulate a Mothership stress roll.

Ooh! Thank you. I’ll put this to good use!

After I finally wrapped my brain around the Mothership stat block, it‘s not terribly difficult. I was weirded out by the minimal one-line stats in percentages. I guess being weirded out is appropriate for a system used for creepy horror. LOL.

Anyhow, I’m cribbing this. I’ll share whatever I end up with. Much appreciated!
