Of Kings and Men
Consult DM before adding something to make sure it is allowed! No, Really! Now read the rest of this!
To hammer it home: Please remember to at least link the DM to your character sheet after making a choice outside of PHB, PHBII, ELH, CA, CS, CM, CD, CC, CW, CA, SC and the DMG! Even then, you should probably show me what you picked anyway.
Note that choosing races from these books is not allowed unless they have a page on the wiki.
