For five seasons our heroes did whatever it took to survive on Earth... and nothing worked. Earth was unsurvivable, lost to them forever.
What was not lost: hope.
After 125 years in cryosleep, traveling through the stars, our heroes woke up to a new home, a final gift from dearly-departed friends.
A place where they can try again. They're given one simple task: do better. Be the good guys.
With this credo in mind Clarke (Eliza Taylor) and Bellamy (Bob Morley) lead a group down to this mysterious world, hoping to start anew, to finally find peace.
But old habits die hard and when they stumble across an idyllic society, it quickly becomes clear that not everything on Sanctum is as perfect as it seems.
Despite their determination to do better, threats both seen and unseen will once again force our heroes to fight for their lives and the future of humanity.
In the Season 6 premiere, "Sanctum": Still reeling after receiving Monty's message, a small group goes down to explore the mysterious new planet.
Back on the Mothership, several members of Wonkru face the consequences of their decisions.
