ORLA is a gas giant in the Terris system.  The hypnotic patterns of its swirling color bands have always attracted the attention of stargazers there, and those with the means to do so have found themselves drawn to personally visit Orla.  Once there, those most susceptible to Orla's influence actually take up permanent residence, orbiting endlessly and writing poetry about it.  These people are uniformly assessed as being incurably insane, but their poetry is so hauntingly beautiful that the people of Terris lovingly support them.  Supply ships crewed by staid and sober-minded individuals bring the poets food and other necessities, and return to Terris with more books of Orlan verse.
