Gandalf is a wise wizard though most would say otherwise about the man since he's often seen smoking from his pipe and seemingly oblivious about things around him but he knows when the situation is serious and can often persuade his way through things because of this knowledge, often the mediator.

Blibo is a hobbit, though they are usually partying, eating, drinking and enjoying themselves back at his home land, the shire, he loves knowing more and adventures. He's very kind and caring which most of the dwarves at first didn't approve of but they got used to it.

Bard is a human who joined the group to help them with defeating the dragon, though most of them are wary of him at first because he is a man.

Legolas is a elf, the prince from his homeland and decided to also help with this dragon even though elves and dwarves aren't the greatest around each other though it was mostly cause the threat the dragon posed.

Honestly, too lazy to type all that yall
