When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

And as the power of science and technology receded, magic rose up in its place. Some of it is good, like the witchcraft worked by Lana Bingham, practicing in the loft apartment she shares with her lover, Max.
