This does not feel right. You are correct that this sort of thing is often glossed over, but the Whorl is a STL generation starship and is not at the "magical" level of technology that, for example, the Ship in UOTNS is. > It's been previously discussed that Lune hasn't sufficient > gravity to retain an atmosphere; given that gravity manipulation > is featured discretely in Severian's time, it's possible that > Lune's gravity was increased during the age of wonders > to keep the air held down. Actually the moon would, I believe, hold an atmosphere for quite a long time, but not for geological timespans. One simple posibility is that a lot of smaller bodies were dumped upon it, increasing its mass and its budget of volatiles. This offers a way of terraforming it at the "Terran" level of technology and also of increasing its gravity. hartshorn --
