AU Dr. John H Watson is still human and still a doctor, though not currently in practice. Originally from Glassighe, he was injured in the elf war or at least some war in a far land, and he nearly died a few times, but he's recovering and married to Cerrit, local Enforcer.

He himself is a novelist. The details of these books is unclear at present but it's probably very exciting adventure and possibly some mystery.

Later update: NOT HUMAN. he is a selkie. Watson is a selkie and Cerrit has his sealskin totally voluntarily and it's gay
