Attention. The sequel to this story has been uploaded. . You all have been great readers and SmaugXToria fans. I do have a confession though. This story wasn't really a SmaugXOc type story, Smaug didn't have feelings for Toria, she had a glint of admiration for him, but only as a young boy would for Superman or Batman.
Toria does not live, sorry for not explaining that. She merely lived long enough to faintly hear the dwarfs' farewells, then died, knowing she had lived up to her greatest potential, smiling.
As for Kili, his guilt had strengthened him. He went out to resume adventuring, after seeing Erebor of course. His exact location remains unknown, but he can be seen if a good soul is in danger or if a great meal is being brewed.
Bilbo returned to The Shire, with a chest of Troll gold, a set of rings from Thorin, and a heavy heart. Not long after though, happiness came back into his life when he adopted his new, young nephew, Frodo.
Toria's spirit watches happily over them and keeps them from trouble as much as possible, though it may be hard once young Pippin comes along.
Gandalf is still the puppet master of Middle Earth.
The dwarfs returned to Erebor with their families. Dwalin found a nice little dwarven lady from the iron hills. Fili is in 'princess training' for the future apointment of the throne.
So, i believe i have answered almost all of your questions, if not please feel free to ask me.
