This shipwreck will make them realize the importance of people working together and looking out for each other's good. Potentially early in the campaign, they may encounter an evil person, too. The paladin dip will only be 2 levels worth (levels 8 and 9) before returning to bard.
As far as deities go, I'm partial to NG or CG, maybe some kind of patron deity of art and music, since Stylianos is still predominantly a bard.
I intend to be mostly ranged combat.
I still need to add my spells. I keep forgetting.
