Of course, in a RP situation you shouldn't bring outside info into the game.
I propose a secret message that shows you as a Bay Watcher, for insertion into regular conversation.
"You look like a mighty warrior indeed"?
Hmmm, if the game developer knows your secret phrase, is it still a secret?
Actually today,
someone on the FTO forums made the suggestion that, via divine intervention, a whole village of characters could be transformed into a new race.
It actually sounds like a very good RP idea, instead of simply spawning a new race out of nothing.
Imagine forming a Bay12 village in the game using the *cough* secret phrase *cough*. Since we're all into Dwarves, the community would probably be really big into mining and crafting stone and precious metals. One day you log into the game and the gods have transformed your village into a new Dwarf race in response to the way you have been playing.
This method of creating new races could be applied across the board. A village of mean-spirited warriors could be transformed into an Orc race, or a village of fishermen could become a race of sea creatures.
Of course all of this would happen very gradually when the game needed a new race to spice things up.
