Well, here's what I have so far (apologies ahead for the long post).
This is Jenni “Mayberry” Berette- the post-apocalyptic flower child. When she was 8, she had acquired what was left of a book about gardening (which was written before the apocalypse). Ever since then she was been absolutely fascinated by the plants that had grown on the earth before everything went to crap. She holds a particular fascination with flowers above all else. Being an artist by nature, she often makes flower-shaped trinkets and jewelry out of whatever scrap she can find. She one days hopes to either be able to A.) sell her flower jewelry and B.) be able to see an actual flower in her lifetime.
Haven’t really thought of a description for this guy. Kept it pretty simple tonight, as I’ve been pretty sick.
Glibnara is a goblin (or gobliness, if you want to be polite). She is considered to be very attractive by the standards of her fellow goblins. Unfortunately she is not too bright. She has the mentality of a particularly savage 5-year-old and has great difficulty understanding abstract concepts. She especially fears music, which she thinks is some sort of ear magic.
Morris Williamson is a man, a man who does not know exactly what he is. He’s not sure if he’s a mutated human, a strange new species, an alien, a scientific experiment gone wrong, or any other possibility. His lack of identity causes him great depression and confusion. Despite all this,he tries to do his best to achieve his goal in life- living a relatively normal, day-to-day life amongst other humans.
Glooble is a monster, but she is neither fearsome nor does she eat people. She’s, in fact, quite gentle. Her favorite food is cake with strawberry frosting.
Martin Bauer is a German foreign exchange student in a Wisconsin high school. While in Germany, he had gone through years of therapy to help cope with his social anxiety. Even though he was able to build up his confidence in Germany, he found that his social anxiety has re-emerged in the United States. He does have a rather good grasp of the English language, he often uses a perceived language barrier as an excuse to avoid conversation. Despite his lack of confidence in social situations, he’s still rather well-liked by most of his class mates, as he’s a good athlete and a rather pleasant person all around.
Mergla is a creature made by a powerful mage. It’s only purpose is to protect said mage’s treasure, even after the mage’s death. The mage’s treasure contains powerful magical artifacts, too dangerous for just anyone to use. It is said that only those who can pass Mergla’s tests of power will be able to wield the artifacts.
Nobody knows what Horse is, but everyone has the same reaction to him- “No sir! I don’t like it!”
... I may or may not be having entirely way too much fun with this challenge so far.
