Nice start Dave, I can see that you're going to do a good job on it already.

I like the idea of him standing guard at some gates, now that you've said it I keep thinking of the fortress on Skull Island from the King Kong movie. Maybe it could be like it was set way before that film when his family were still alive, mixed with Planet of the Apes.... Sorry, got carried away a little there....

All good though, look forward to more!
