Funny quote from the last time this showed up 
I'm pretty sure you can't tame intelligent beings.<P>Oh, and invaders are always hostile, even if you do tame them. I learned that the hard way with some Beak Dogs modded to be tamable.<P>I´m not always sure if goblins should be classified as intelligent

Goblins happily run away as soon as two or three of their number get killed.<P>In this world, they're veritable geniuses.
