<Jibbly points to the large turds covering the base.>
We built the Sludgewerks near a wyvern habitat. Now our initial blueprints for the Sludgewerks were drawn up so as not to disturb the wyvern habitat as the beasts are apparently sacred to tauren and orcs. Do you know what's sacred to me? Not getting pooped on, that's what!
Between you, me and the wall, the wyvern must die!
