Night gathers, and now your watch begins.

You step into the elevator and take a last look around the courtyard of Castle Black before a bone-rattling ride lifts you 700 feet, depositing you in the whipping wind of the frigid north, high atop The Wall.

Then, as the red flames of torches flicker in the distance, you hear two telling blasts from the watchmen's horns. The wildlings are coming.

For thousands of "Game of Thrones" fans, that brief immersion into the life of a Night's Watch soldier in the HBO show is becoming a reality this week, thanks to an exhibit at the South by Southwest Interactive festival that employs one of the hottest gadgets in tech.

"Ascend the Wall" is part of a traveling exhibit promoting the wildly popular fantasy epic, which returns for its fourth season next month. It's built using Oculus Rift, a virtual-reality headset that has captured the imaginations of gamers since its $2.4 million debut on Kickstarter in 2012.
