Last week, executive producer Marc Guggenheim debuted the official logo for "DC's Legends of Tomorrow's" Justice Society of America. Now, following casting announcements for Stargirl and Commander Steel, Guggenheim offers fans a glimpse inside the JSA headquarters, including the show's take on the team's iconic meeting table.

In its debut season, "Legends of Tomorrow" took the "Arrow"-verse up, up and away -- as well as back and forth through time. The Waverider and its host of heroes will stay the course in Season 2, which promises to include more familiar heroes and historical figures.

Just when the Legends of Tomorrow regrouped to find a new adventure, the new adventure found them: A Waverider from the future came crashing down onto the dock where they stood, and a man they had never met before emerged -- Rex Tyler, aka Hourman.

Although we haven't met any of his friends, Hourman assured the Legends he wasn't acting alone -- and his group will be familiar to DC Comics fans: the Justice Society of America, an elite group that has counted among its members Jay Garrick, Power Girl and the original Sandman. Accordingly, then, Justice Society members Obsidian, Stargirl and Doctor Mid-Nite will join the Legends in Season 2.

Starring Brandon Routh, Caity Lotz, Arthur Darville and more, "Legends of Tomorrow" returns to The CW for its second season on Thursday, Oct. 13, at 8 p.m. ET/PT.
