A Gnome's Respite

You see, <name>, I'm a member of the Enlightened Assembly of Arcanology, Alchemy and Engineering Sciences, and it's my goal... nay, my DUTY! to show the night elves that a blend of magic, mixtures, and mechanisms can help save their forests. But it's a hard fought war, and the goblins reproduce like rabbits it seems. I haven't even had time to build my newest inventions! I need some time to plan and organize. But to do that, I need your help keeping the goblins at bay in Windshear Crag to the east...
