Hot on the heels of the apocalyptic hoopla of 2012, ChimaeraCon rises from the flames with “Aftermath,” a weekend offering survivors “an escape to a new world with new possibilities.” The not-for-profit gathering champions tabletop gaming and organizes vendors, artists, and activities to delight fans of science fiction, anime, cosplay, and the steampunk lifestyle. With an array of special guests and niche panels, like “How to Be a Ninja” or “Cosplay on a Budget,” one need not be familiar with The Licktoad goblins of Brinestump Marsh, own a 20-sided die, or have a favorite LARP (live-action role-playing game). In fact, some of the more imaginative games (like Khet, an Egyptian take on chess played with lasers) can be learned in a few minutes. No geekiness or experience required. $10-$35, 5pm-2am Fri, 8am-2am Sat, 8am-6pm Sun, Courtyard by Marriott, 11605 State Hwy. 151, (210) 509-3700, chimaeracon.com.
