I'd like to submit an application as either a Human Monk, or a Gold Elf Psion. Either character is fine with me, I just offer two ideas to help round the party out better.
As the Monk my character is pensive and pragmatic. He is a highly disciplined and focused individual who is loyal to the party. His Temple would have been obliterated by the Queen's forces, and now he wanders the land trying to protect others from her oppression. He probably identifies with the cleric of the party, and is fond of listening to tales of enlightenment.
The Psion is highly intelligent, and lacks social tact. He is almost blind to his own behavior concering social interaction, and he commonly says the wrong thing at the wrong time. He sees his role in the party as the advisor, and loves to offer his knowledge of obscure facts. I'm thinking of having him be either a Telepath or a Clarisentient.
