I don’t have this feeling for everyone.  Now that I am recalling him, he was not so much superior as different.  I was so impressed that I rose and talked to him standing.  He inquired the direction of the mountain Adage.  He went on to say, ’They say Muspel-light is sometimes seen there.  What do you know of such a thing?’ I told him the truth—­that I knew nothing about it, and then he went on, ’Well, I am going to Adage.  And tell those who come after me on the same errand that they had better do the same thing.’  That was the whole conversation.  He started on his way, and I’ve never seen him or heard of him since.”

“So you didn’t have the curiosity to follow him?”

“No, because the moment he had turned his back all my interest in the man somehow seemed to vanish.”

“Probably because he was useless to you.”

Corpang glanced at Maskull.  “Our road is marked out for us.”

“So it would appear,” said Maskull indifferently.

The talk flagged for a time.  Maskull felt the silence oppressive, and grew restless.

“What do you call the colour of your skin, Haunte, as I saw it in daylight?  It struck me as strange.”

“Dolm,” said Haunte.

“A compound of ulfire and blue,” explained Corpang.

“Now I know.  These colours are puzzling for a stranger.”

“What colours have you in your world?” asked Corpang.

“Only three primary ones, but here you seem to have five, though how it comes about I can’t imagine.”

“There are two sets of three primary colours here,” said Corpang, “but as one of the colours—­blue—­is identical in both sets, altogether there are five primary colours.”

“Why two sets?”

“Produced by the two suns.  Branchspell produces blue, yellow, and red; Alppain, ulfire, blue, and jale.”

“It’s remarkable that explanation has never occurred to me before.”

“So here you have another illustration of the necessary trinity of nature.  Blue is existence.  It is darkness seen through light; a contrasting of existence and nothingness.  Yellow is relation.  In yellow light we see the relation of objects in the clearest way.  Red is feeling.  When we see red, we are thrown back on our personal feelings....  As regards the Alppain colours, blue stands in the middle and is therefore not existence, but relation.  Ulfire is existence; so it must be a different sort of existence.”

Haunte yawned.  “There are marvellous philosophers in your underground hole.”

Maskull got up and looked about him.

“Where does that other door lead to?”

“Better explore,” said Haunte.

Maskull took him at his word, and strolled across the cave, flinging the curtain aside and disappearing into the night.  Haunte rose abruptly and hurried after him.

Corpang too got to his feet.  He went over to the untouched spirit skins, untied the necks, and allowed the contents to gush out on to the floor.  Next he took the hunting spears, and snapped off the points between his hands.  Before he had time to resume his seat, Haunte and Maskull reappeared.  The host’s quick, shifty eyes at once took in what had happened.  He smiled, and turned pale.
