Next month marks the beginning of the end for Oliver Queen. In Arrow's final season, Star City's Green Arrow will embark on an adventure with the Monitor in an effort to prevent a "Crisis on Infinite Earths" from destroying the multiverse. Now, the Season 8 trailer has offered a look into the Emerald Archer's mysterious last ride.

The trailer opens at the Queen family's mansion, a set that hasn't been utilized since the show's 100th episode in Season 5. "The only way that this is bearable for me is if I am certain my sacrifice -- my death -- will protect the people I love," Oliver says in a voice over narration.

As Oliver speaks, the trailer cycles through some old settings, including his Verdant night club. Here, Colin Donnell's Tommy Merlyn looms, glaring at Oliver with suspicion. In another cut, Oliver awakens in his Season 3 bedroom in Hong Kong. When the trailer returns to the Queen Mansion, Oliver gazes at a photo of his wife Felicity and their daughter Mia, making it clear this is indeed the Oliver who left with the Monitor in Season 7.

"There is a Crisis coming," Oliver points out, to which John Diggle responds, "We're facing the destruction of pretty much everything." A montage of action sequences shows the return of Willa Holland's Thea Queen, their mother Moira and Katana, aka Tatsu Yamashiro.

The trailer explores more than Oliver's past. Indeed, it offers a glimpse into the future, where a grown Mia has taken up her father's mission to protect Star City. These flash-forwards include more of the Deathstroke gang and its leader, Diggle's son J.J.

Arrow will close out with a 10-episode final season. The Arrow series finale will not be part of the five-show "Crisis on Infinite Earths" crossover. That will take place during Arrow Season 8's eighth episode, then the series will wrap up in episodes 9 and 10 to give it "a proper series finale."

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.
