"Ashcan" Pete and Amanda Sharpe took on Nyarlathotep with a visiting exhibit expansion. The only weapon between us to start with was a Derringer. And Duke had to get sacrificed to stop 'The Stars Are Right' after it added a doom token. But things just seemed to go our way. We got no double doom token mythos, when the Arkham river washed up two exhibit items, one was a Parchment (the only Elder item we used all game). We got lucky and both missed a dual color gate card by one card when we were in the appropriate realms. And we both learned the value of sneak, we only killed 2 monsters between us, a maniac, and an elder thing.
It was our 8th try, and we sealed for the win. Our only other success during those 8 tries was a final battle win vs. Shudde M'ell. But we wanted to prove we could seal. We'll definitely be adding a couple more investigators to take on Dunwich! 
Sorry for the unexciting and vague status report, but it's late. Gotta work tomorrow.
