Here, I have a better version of the main cast, that's easier to decipher.
Just starting from right to left, here.
The camel is
Argus, who used to be a Dragonborn druid, played by my 9 year old nephew. He had to stop playing, so the justification is that the Paladin found a cursed dagger, accidentally tossed it, and it stuck into Argus, who became trapped in Wild Shape as a camel. The Paladin still has the dagger, and has named it the Camel Stabber Dagger, which turns whatever it stabs into a camel.
The skeleton is
Sir Dandybones, or Sir Dan, played by my fiancee. He's a puckish rogue who enjoys being theatrical, playing his bagpipes, and macking on fleshy babes. He doesn't exactly recall who he was as a living human, since that was aeons ago, and so he just kinda roams the world looking to entertain and maybe bone someone. He has a fairy dragon that lives in his skull named
Maxilla, who gorges herself on gold coins. He also has a bag of holding in his ribcage.
The gnoll is
Fir. Long story short, he was the youngest member of a gnoll pack that tried ambushing the group, and Fir is the only survivor of the massacre that ensued. After seeing his father die, he was kinda wary of, you know, doing anything to help the group, but after coming to terms with the fact that his family was in the wrong, he came around. However, he doesn't like Vareen or Sir Dan, who decided to skin his father and use it as a costume for Dan. He's now a rogue for the group.
The big blue guy is
Vareen, aka Popesquatch. He's a firbolg cleric and also the guardian of a forest village which acts as the focal point for a nature cult that worships a wolf god that devours anyone who knows and defies their law. He isn't too happy to be on the quest away from home, and acts as the main attacker of the group.
The purple dragon is
Ife, who isn't really a dragon, but a "dwagon", a bastardization of "dvargon" used by the populace to describe a group of amphibious pack-hunting reptilians that inhabit a cave system in the northern regions of the country. She is basically a reptilian tiger that acts like a big ole' kitty cat, and has a paralytic in her saliva that doubles as a healing salve. She was sent to travel with the group to see the world for her coming-of-age.
The jellyfish and the knight are
Cnidar and
The Paladin, respectively. The Paladin is a knight that obeys the goddess of vanity, and seeks to destroy whatever he sees as ugly. Cnidar is a flumph, a kind of creature that feeds on positive emotions, that the group rescued from a displacer beast. The last of it's family, Cnidar stuck with the group, and frequently perches on top of the Paladin's head, feeding on his inherent narcissism and drive.
The clown is
Dogg, a midget from the Clown Dimension, played by
@Oglooger . He is often used as a projectile by Vareen, and is only in it for the hookers. That's the thick and thin of it.
The skull is
Cosmo, aka
The Eternal Universal Cosmodium. He's a demilich that got locked in a box for a few hundred years before being found by the group. He's kind of insane, and likes to eat hearts.
Green Fabio there is
Chuck. He is the result of the Paladin entering a cooking contest, and rolling so badly that his stew was considered a trash can that everyone else dumped their dishes into. Since a lot of the contestants were using magic in their dishes, the stew became a literal primordial soup that gave birth to Chuck, who sees the Paladin as his father and god. This, incidentally, allowed Cnidar and the Paladin to gain sparks of divinity. Chuck is a barbarian, and fights to protect them.
