token of friendship from a dwarf... let's see...

I - dwarves give you a canal\
II - no dwarves
III - dwarf is a class
IV - I think Cid is a dwarf, and he gives an airship
V - Don't recall dwarves
VI - No dwarves
VII - no dwarves
VIII - no dwarves
IX - dwarves give you a marriage, not sure exactly what else
X - no dwarves
XII - no dwarves
XIII - no dwarves

Hmm, just grabbing a few straws for anyone that wants to bend them.
