When we had followed the thing into the archway and turned both our torches on the indifferent and unheeding group of three we saw that they were all eyeless albinos of the same unknown and gigantic species. Their size reminded us of some of the archaic penguins depicted in the Old Ones' sculptures, and it did not take us long to conclude that they were descended from the same stock -- undoubtedly surviving through a retreat to some warmer inner region whose perpetual blackness had destroyed their pigmentation and atrophied their eyes to mere useless slits.
