Golden Sun/Gondowan Passage

This is the crossing from the continent of Angara, where the entire game has so far taken place, to the southern continent of Gondowan.

Gondowan Passage
Much like the Kolima Bridge, this is just a drawbridge across a river, manned by guards from Tolbi. Iodem is waiting for you here. When you talk to him, he will "join" your party, in the same way as Kraden did way back in Sol Sanctum: He is traveling with you, but does not fight. If you try to go back to Angara with him, he will leave and wait at the passage. Otherwise, he will stay with you until the end.

Gondowan Cave
Head East from Tolbi and the Passage to reach Gondowan Cave. This is an alternative route to return to Angara, since you can't take a boat back across the Karagol.
