Despite his partnership with the mutliverse-hopping Monitor, Oliver Queen's last mission will take place largely on his own world: Earth-1.

According to TheWrap, showrunner Beth Schwartz confirmed Arrow Season 8's setting at The CW's Television Critics Association press tour panel. She also revealed the premiere will pick up shortly after the Season 7 finale, which sets it in 2019.

This only deepens the mystery surrounding the show's final season. After all, long-dead characters from across the show's history, including Moira Queen, Tommy Merlyn and Prometheus, will return in some capacity. If Oliver isn't going to other Earths, then perhaps some time travel is involved.

In the Season 7 finale, the Monitor appeared at Oliver Queen and Felicity Smoak's safehouse. He told Oliver to make good on his end of their deal from "Elseworlds," informing him that they would travel to other worlds to warn of the upcoming Crisis. Worse, he revealed Oliver would die in the conflict to come.

When Season 8 picks up, Oliver will have just left Felicity and their daughter Mia behind. As such, he'll likely still be reeling from his separation from his family, even as he races to save the multiverse with the Monitor.

Returning Tuesday, Oct. 15 at 9 p.m. ET/PT on The CW, Arrow stars Stephen Amell as Oliver Queen, David Ramsey as John Diggle, Rick Gonzalez as Wild Dog, Juliana Harkavy as Black Canary, Katie Cassidy as Black Siren, Katherine McNamara as Mia Smoak, Joseph David-Jones as Connor Hawke and Ben Lewis as William Clayton-Queen.
