Island Nights' Entertainments by Robert Louis Stevenson

Keola was married with Lehua, daughter of Kalamake, the wise man of Molokai, and he kept his dwelling with the father of his wife. There was no man more cunning than that prophet; he read the stars, he could divine by the bodies of the dead, and by the means of evil creatures: he could go alone into the highest parts of the mountain, into the region of the hobgoblins, and there he would lay snares to entrap the spirits of the ancient.

For this reason no man was more consulted in all the Kingdom of Hawaii. Prudent people bought, and sold, and married, and laid out their lives by his counsels; and the King had him twice to Kona to seek the treasures of Kamehameha. Neither was any man more feared: of his enemies, some had dwindled in sickness by the virtue of his incantations, and some had been spirited away, the life and the clay both, so that folk looked in vain for so much as a bone of their bodies. It was rumoured that he had the art or the gift of the old heroes. Men had seen him at night upon the mountains, stepping from one cliff to the next; they had seen him walking in the high forest, and his head and shoulders were above the trees.
