Resolution

The strong waves and currents take the boat with Edmund, Eustace, and Lucy on to an island with short grass and rich soil. They encounter a sheep, and it transforms into Aslan. The lion takes the children home through a magical portal in the sky, but tells the children they cannot come back to Narnia again.

Once the children are back in their own world, everyone notices how much Eustace has changed into a better person, except for Eustace's auntie, who thinks that Edmund and Lucy had something to do with it. Back in Narnia, the Dawn Treader with everyone in it, comes back to Ramandu's Island unharmed and the three lords woke up from their sleep.
