It seems that these men have an aura not of earth about them, though that is not the reason why no cat will sail on their ships. The reason for this is that Inquanok holds shadows which no cat can endure, so that in all that cold twilight realm there is never a cheering purr or a homely mew. Whether it be because of things wafted over the impassable peaks from hypothetical Leng, or because of things filtering down from the chilly desert to the north, none may say; but it remains a fact that in that far land there broods a hint of outer space which cats do not like, and to which they are more sensitive than men. Therefore they will not go on the dark ships that seek the basalt quays of Inquanok.
