Dirk Gently's Holistic Wiki

The Onx is fictional condition in the Dirk Gently books.

It is a condition that affects gods who have tired and can't stand their godhood anymore. In the last stage of the onx, the god lies down and after a while a tree grows out of their head. The god is dead then and rejoins and merges with the earth and nature, eventually becoming a spring of water.

Tsuliwaënsis explains about the onx to Kate Schechter in the The Long Dark Tea-Time of the Soul.[1]
