Odysseus just watched Poseidon kill almost all of his men in horror. He was about to kill the rest of his crew, so Odysseus used what was left in the windbag to get away from Poseidon. He ended up landing on Aeaea, Circe's island. Obviously, they didn't know that, and Odysseus sent Eurylochus to go make sure the island is safe. Eurylochus returned, but none of the men were with him.

Odysseus: Eurylochus, back so soon? Where's the rest of your crew? And by the gods, what happened to you?

Eurylochus: We came across a palace. Inside we heard a voice! It seemed to show no malice... To greet it was our choice. But nothing could prepare us for thе power that awaited inside!

Odysseus: What did this palacе hide?

Eurylochus: Sir, since we left home we've faced a variety of foes from a wide range of places! Gods, monsters, you know the roster, hostile creatures that we could resist! But this was a hell of a twist, cause we are weak to a power like this!

Odysseus: What was it?

Eurylochus: A woman.

Odysseus: ... What?

Eurylochus: She had us in just two words!

Just then, they heard your voice. The voice of minor goddess. You're the daughter of Helios, and a powerful sorceress who was cast away because you turned the nymph, Scylla, into a monster even Poseidon feared. Your father, Helios, never liked you either. Helios only cared about power.
