A good basic plot idea - some of the details are not my cup of tea, but the general premise is good.
What Muro said.
A good starter adventure - especially where conflicts between orc/humans etc is more then just 'they are evil..'

A good basic idea that can be the start of great events.
A very flexible, low-key adventure!
