And the keyrings are already gone.
Harrumph. Anyway: Widdershins is an awesome webcomic, Curtain Call was a fun little brawl featuring Our Heroes vs. The Seven Deadly Sins, and the Kickstarter will get you the latest book and PDFs for the rest. I heartily recommend it, whether or not I got a free keyring*.

*[UPDATE]: …Arrangements were made on the keyring thing.
