Finish up your cosplay and grab your favorite comic books—Emerald City Comic Con is back! ECCC is a time-honored (and super nerdy) Seattle tradition, held at the Seattle Convention Center on March 5-8 this year. Attendees will be preparing for four days of panels, screenings, fan meetups, cosplay contests, after-dark partying, and perusing the wares of Artist Alley, where local artists come together to hang out, create, and sell fun products.
