I just read all your Cetra Restoration stories. They are fascinating in a squicky sort of way. All the humans met so far are slaves.
But if Tseng is condemned for 10 years, isn't he very close to the end of his term? While you mentioned in Indenture, that a First Concubine will normally stay while his/her master is alive, Tseng isn't that important to Sephiroth or Cloud, that they would want to force Tseng to stay.
