Aearhin regards the warforged with a slightly puzzled and indeed apprehencive look, not sure if the machine might be joking or if it is even capable of it. "Uhm, I'd really rather not." Just to be certain he backs up half a step. "About these Sahuagin, they are despicable and evil creatures, the enemies of all good aquatic races. Much as I hate to admit it, they are to be considered intelligent and often wield weapons. On their own the are not much to worry about or even in small groups, but then again if there are larger numbers, who can say."
Aearhin will reveal any usefull information he has on the abilities of the Sahuagin, but I will leave it up to the DM to decide how much he actually knows.
