Pacifica is a world dominated by a single huge ocean.  I explore under water, usually with other scientists, sometimes alone.  It’s nice not having to be worried about drowning.  Sometimes I just visit the Arnam who live there now.  Often they help us explore.  With the Arnam, I have visited ancient underwater ruins that have never been noted by any publication.  Humans used to live on Pacifica, long ago.  One day, I want to know who they were.
