The ability to speak and comprehend Takargu, a guttural language native to
goblins and related species.  As with Angrak, more civilized peoples often
understand Takargu only because of their species' long, involuntary familiarity with
goblinish races.  Takargu is a tongue somewhat like, but distinct from, Angrak;
perhaps illustrative is that the concept that Angrak has the most words for is
'kill', whereas the best-expressed idea in Takargu is 'steal'.
