First a little history and geography lesson. The Kingdom of Avalon is a mystical and mythical place surrounded by a strange mist. People from worlds and dimentions all over are transported via this mist into Avalon. It is said that the traveler will find and enter Avalon when they are needed or need to.
In and amongst the Baronies throughout Avalon are scattered many races: Human, not-so-Human, Elven, Fairies, Giant, Half-Giant, Goblin, Kender, and so on. This is just a short edited list of the diversity that live within Avalon.
What does this have to do with "A character in a drama..."? Well, race is just a small part of it. It is up to the individual to imagine what the characters look like and how they act. Put all the different characters together in a pot and your have interaction. Impromptu lines, action and reaction lead to an improv.
Monsters grunt, goblins speak in a broken language, the royal army chase down maruaders and monsters. Add to that the conflict of combat and you have Dagorhir, as the Kingdom of Avalon plays it.
Other Kingdoms might center on the combat aspact. Others focus on the historical, such as the Romans. We, in the Kingdom of Avalon, enjoy a mixture of each aspect.
Costuming and make-up do alot to portrait a character on the field of battle. Scots wear kilts and wode (face paint), goblins wear tattered clothes and base green make-up. Some elves wear rubber or foam ear pieces. It's all up to one's imagination. When one walks on the field of battle, the final effect should be not one of "What are you?", but instead, one of "Oh, your a goblin, aren't you?" Or "Hail, Scot."
Just use your imagination and let it fly.
That being said, you may or may not know of the current citizans of the Kingdom. Included in the list of travelers that have made Avalon their home are:
