A few hours after they had woken up in the morning - at least they assumed it was morning, as there was nothing nearby to tell the time from - another robed figure opened the door.  "Lina, it's time to go back to your room.  You'll be able to see your sister again if you win tonight.  And as you were asking, every win will give you another key to unlock her chains," she said before taking Lina back to her cell.  Once again she was given a fairly generous meal while waiting, and Roland came for her again a few hours later.  "Time for your next fight.  Feeling ready?" he asked as he led her through the dungeons to the arena.  Keeping her bearings was difficult, but it seemed like they were going in a different direction than the last time she was brought to the arena.  The antechamber was the same however, with the same weapons and armor laid out for her to pick from once Roland locked the door behind her.  "Be careful, this guy's quite a bit tougher than the kobold you fought before," he warned.
