Jycinda's collar is exclusive to the guild. This means she serves the guild and not the complex proper.
-- Serve the Master Assassin first and foremost. Other Assassins who may be here and the Apprentices comprise the remainder of the guild.
Sexual use is restricted to the guild. She can serve food and drinks regardless.
Her duty is to remain pleasing and exemplify what a good slave is
Guild slaves don't travel without the Master Assassin's direct permission.... and likely his presence as well. She may however, attend the market if another Assassin or Apprentice of Shadowmoon is present, but no where else.
