Ah sorry, Corty. It's a habit of mine. I am usually on the other side of the hero's sword if you know what I mean ?
Ehhhhh... yeah! Kill this awesome one of a kind probably dragon that's been alive for who knows how long- does it qualify for destruction of historical monuments? I mean, yeah, end the life of this unique and amazing sapient being you uneducated swine, you murderer!
Don't mind its life, there is an entire pack (or however you primates call yourselves? Schools? Tribes? Whatever) there is a whole tribe of you monkeys you need to defend, even if they all will die in less that like 80 years while this dragon could still be around in thousands of years. Go for the throat!
