It was then that I began to study the mirror with mounting alarm. The slow ravages of disease are not pleasant to watch, but in my case there was something subtler and more puzzling in the background. My father seemed to notice it, too, for he began looking at me curiously and almost affrightedly. What was taking place in me? Could it be that I was coming to resemble my grandmother and uncle Douglas?
One night I had a frightful dream in which I met my grandmother under the sea. She lived in a phosphorescent palace of many terraces, with gardens of strange leprous corals and grotesque brachiate efflorescences, and welcomed me with a warmth that may have been sardonic. She had changed - as those who take to the water change - and told me she had never died. Instead, she had gone to a spot her dead son had learned about, and had leaped to a realm whose wonders - destined for him as well - he had spurned with a smoking pistol. This was to be my realm, too - I could not escape it. I would never die, but would live with those who had lived since before man ever walked the earth.
I met also that which had been her grandmother. For eighty thousand years Pth'thya-l'yi had lived in Y'ha-nthlei, and thither she had gone back after Obed Marsh was dead. Y'ha-nthlei was not destroyed when the upper-earth men shot death into the sea. It was hurt, but not destroyed. The Deep Ones could never be destroyed, even though the palaeogean magic of the forgotten Old Ones might sometimes check them. For the present they would rest; but some day, if they remembered, they would rise again for the tribute Great Cthulhu craved. It would be a city greater than Innsmouth next time. They had planned to spread, and had brought up that which would help them, but now they must wait once more. For bringing the upper-earth men's death I must do a penance, but that would not be heavy. This was the dream in which I saw a shoggoth for the first time, and the sight set me awake in a frenzy of screaming. That morning the mirror definitely told me I had acquired the Innsmouth look.
So far I have not shot myself as my uncle Douglas did. I bought an automatic and almost took the step, but certain dreams deterred me. The tense extremes of horror are lessening, and I feel queerly drawn toward the unknown sea-deeps instead of fearing them. I hear and do strange things in sleep, and awake with a kind of exaltation instead of terror. I do not believe I need to wait for the full change as most have waited. If I did, my father would probably shut me up in a sanitarium as my poor little cousin is shut up. Stupendous and unheard-of splendors await me below, and I shall seek them soon. Ia-R'lyehl Cihuiha flgagnl id Ia! No, I shall not shoot myself - I cannot be made to shoot myself!
I shall plan my cousin's escape from that Canton mad-house, and together we shall go to marvel-shadowed Innsmouth. We shall swim out to that brooding reef in the sea and dive down through black abysses to Cyclopean and many-columned Y'ha-nthlei, and in that lair of the Deep Ones we shall dwell amidst wonder and glory for ever.
