But when I took my aim, I saw the most incredible thing: it started building something out of the mud in the swamp, faster than you would believe. You know as well as I do that those things are supposed to be stupid violent brutes, but let me tell you, it was thinking... in the time it would take me to pitch a tent, it had built a mud building so solid that you couldn't knock over with an ox! I couldn't believe it. What? Of course I killed it! Can you imagine what a whole group of those things could do?" Instinct: To build vast structures

Spiderhorses are pack-arachnids used by the dwarves to navigate rough terrain. Though not particularly fast, they're much faster at getting up hills and across scree than most animals. Spiderhorses are bred to be docile and not particularly bright.

Instinct: to flee danger

• Climb an impossibly steep surface
