A big thanks to  nateday for doing this fantastic bit of art up for us.

The two characters are Jack and his sister, April.

The theme of this year's convention is loosely based off Mad Max: Beyond Thunderdome, which coined several famous lines such as 'Two men enter, one man leaves'. It's a post apocalypse action movie, with not very much to do with the prior Mad Max films, but fun in it's own way.
