This is what it's like behind-the-scenes with a major 'League of Legends' team at the North American championship game

Live from Madison Square Garden, the North American "League of Legends" 2015 championship is happening right now: August 22 and 23.

Tonight's big game is between Team Liquid and Team Impulse: if Team Liquid wins, they're automatically headed to the World Cup of professional "League of Legends" play, LCS Worlds in October. If Team Impulse wins, they're one step closer to securing an invite to Worlds - they have more work after tonight to make that happen.

We're here at the game following Team Liquid, the stars of Tech Insider video series "League of Millions." As such, we had the opportunity to spend some time with Team Liquid ahead of their big game, which gave a fascinating look into the behind-the-scenes life of one of the most popular teams in eSports as they prepare for their biggest championship game yet.

It's a tale of Red Bull, sockless feet, and hand warmers. Yes: hand warmers. Prepare yourself!
