Clarke and a few others have landed on the cold and isolated planet, Nakara in the previous episode, Hesperides. As new planets will be aligning in upcoming episodes, it is only natural to have one named after one. Read the press release for Nakara (7×6), accredited to The CW.
The 100 Nakara official press release:
NOT EVERYTHING IS WHAT IT SEEMS – Clarke (Eliza Taylor) and her friends find themselves on a planet that is not what it seems. Bob Morley, Marie Avgeropoulos, Lindsey Morgan, Tasya Teles, Shannon Kook, JR Bourne, Shelby Flannery and Chuku Modu also star. PJ Pesce directed the episode written by Erica Meredith (#706). Original airdate 6/24/2020.
Analyzing the given and single sentence, Clarke finds out that there is something not quite right with the ice planet. Maybe they ran into some post-apocalyptic polar bears or met more Disciples and they all engage in a war. After all, Anders did quote that last war mankind will ever wage and he wants Clarke to be a key player.
The one thing that we do not do is tell Clarke what to do because she will fight back like a fiery hurricane.
Yet, maybe the helmet has a mind-control mechanism that made Raven chose to go to Nakara. She might have figured out the technology, but not all the kinks. Otherwise, why that planet and not the others?
Oh, that’s right, she chose it on “fun”, not on logic and principle.
The planet itself could be a well-devised trap, set up by the Shepard. There is a reason why there is not an Anomaly stone on the cold place; the Shepard does not want the group to go any further, for they are doing inhumane and unlawful treatments to their friends. Thus, stopping Clarke from seeking the truth.
This is, of course, just a theory, and in the event that it may be a premonition, it is purely coincidental.
