"Nosta Vakhal" Kyle said, slightly bowing to the man.  "I apologize" in the Dwarven of his dimension, or more accurately "I make amends."  Of course, the Dwarves weren't native to Earth, or at last his Earth, so there was the chance what little he had learned of the Dwarven language and culture wouldn't be the same, but he needed to at least try.  He also ignored the dirt that the man was stirring up and getting on his suit and the fact that there was plenty of room to go around him.  "Can I help you?  I'm new here myself, but if I can, I'll assist you."  Maybe on his world the Dwarves were a ruling class?
