Oh No Not Another Fantasy Adventure

The sequel to YADFA in which you, no longer a mere farm boy but now a mighty lord of Harrenden (or nearly anyway) discover an egg in the privy of your new castle (as you do). Seeing no point in keeping said egg, you flush it down the privy. All well and good. Until an angry dragon shows up at your front gates and threatens to eat you if you don't retrieve the egg - which just so happens to be his unborn baby brother. What will happen? Will you find the egg from wherever it's ended up? Will you save yourself and your castle from certain death? Or will you wind up as an after-meal-snack for a certain fire-breathing fiend?
