As Roran watched, the man's arms, neck, and chest shriveled, and his bones appeared in sharp relief-from the bowlike curve of his collarbones to the hollow saddle of his hips, where his stomach hung like an empty waterskin. His lips puckered and drew back farther than they were intended to over his yellow teeth, baring them in a grisly snarl, while his eyeballs deflated as if they were engorged ticks being squished empty of blood, and the surrounding flesh sank inward.

A typical Celestine will devote a large proportion of their time to passing through the inscribed sectors of the planet studying the writings, either alone or accompanied by companions with whom to share comments. This is a favourite pastime among them, and as they travel towards the boundaries of the inscribed regions they can watch the ongoing work of those Celestines that have been chosen to record their ideas _ tirelessly twisting, pausing to gather energy, then exerting themselves again; painstakingly working the same patch of dust several thousand times over to shape each individual furrow; to capture, symbol by symbol, the knowledge they have contributed to the Celestine corpus. There is great pride and precision, as well as immense labour, in their toil. Before they commence work, the piece of ground that will house the writing will be chosen very carefully for its aspect. Then, the most favourable angle to the light will be calculated, for the orientation of the wording. The language used is of the most poetic and grandiose sort, quite different from the vernacular, and the symbols themselves are embellished with flourishes, extravagances and curlicues that are unique to the creator. Celestines love to observe this work, which constitutes the pinnacle of their art and of their ceaseless thought-endeavours, and embodies their very reason for being.
