After the events of Beach Episode, the students have received word from Dr. Venetus. She has spoken with Atlantean officials about opening up relations with the surface world. They have agreed to considering the matter farther, should an initial trial period between Eclipse Academy and the Atlantean Academy go well enough. So, Dr. Venetus has asked for them to make the trip down there (accompanied by a teacher of course) where they will speak to other students about benefits there would be to open relations between Atlantis and the surface world and what it means to be a hero (it seems there is some interest that aspect of it following the popularity of heroes hailing from Atlantis on the surface world, an exchange program perhaps?)

Those against making Atlantis properly known to the world would see to it that this fails, at least that is what Dr. Venetus has warned the participating students about.

Player preference goes to those involved in the Beach Episode mission, then if there are any remaining slots- those who would make the most sense given the setting/mission.
