Kraken Con debuted last October. I wasn't expecting much, but was blown away! I've been attending cons for seven years now, and this was one of the funnest cons I've ever attended! I was so busy that I didn't have time to do any photoshoots!
It'll raise its head again on April 7th at the Oakland Convention Center. Definitely check it out if you're free!
