I have an approval and nothing to do with it.

Recently, Robikku decided to be awesome and approve my Cast app, no questions asked. What character? Who else but everypony's favourite, flamboyant sea serpent, Steven Magnet?

Now, whose ponies live in the Everfree?

...right.

Do any of you have ideas of what to do with Steven?

A look at the greater map reveals that the major river in the Everfree (which can't actually be where we saw Steven, so we'll assume he lives in a river that is a tributary of the major river) runs down to Fillydelphia. He could visit the city then. Or you could arrange something where a small group of ponies go into Everfree for whatever reason and meet up with Steven.

Also, the river network of Equestria actually allows Steven to get into Ponyville, up to Canterlot, Trottingham, Stalliongrad...
