Let me explain.

I've volunteered to protect the Daru.

What? I don't look like the kind of person who'd be interested in animal conservation? Personally I consider myself to be one of the good guys!

But let's move on. Several Worgs have appeared lately.

The Daru will become extinct if nothing is done about it.

I am a member of an association that protects Darus. So I can't simply watch and do nothing!

That is why I am asking you to kill the Worgs for me. You shall be appropriately rewarded.
Yes! I knew it!

Please kill 18 Worgs.

I'm counting on you!

And? Did you manage to reduce the number of Worgs?
Good, very well done.
