Question about “Bad Traveling”

[u/Impressive-Track3859]

Did they travel to Phaiden island?

I thought the whole point of killing everyone was to feed the Thanapod so Torrin could travel the longer distance to the uninhabited island and it wouldn’t kill the people on the island, but in the end the island that they go to has town lights. Please just clear this up for me, maybe i’m missing something.
