It's mostly a thing doing for fun, but will also help me and the writer to understand what is more popular amongst the players. So if we see a particular kind of personality/situation is very popular, we'll try to do something along the same lines in future games, and so on.
Even if I'm the author, I have my preferences too. I voted Loren - Saren, even if it was a *very* close call with Saren - Myrth. But Loren - Saren is really wonderful IMHO. It might be for the atypical situation, you being a slave, and she is your mistress, but seeing her change her point of view and attitude towards Saren,
saren: "Kill me, if you must. I won't ignore your pain, even if you chose to."
"Saren stared at the floor in the next moment, unsure of what would come next. When nothing happened immediately, he feared the worst."
loren "You think ... I would kill you? For this?"
"Saren looked up and saw Loren's pained expression."
"Especially since he thought that, as a man, he would have never have had the privilege to touch her. He reached his hand out to her leg."
"Loren shivered in anticipation just before he touched her skin."
"Saren's fingertips brushed against the top of Loren's foot as he softly placed he hand on her ankle and glided it slowly upwards, searching her leg for trauma. Loren's eyes closed, but not from pain."
"Loren could not help but remember the day her life was saved by a nameless slave. She had broken out of the castle and spurned her studies, but turned down the wrong alley or took the wrong street ... the people there did not care who she was."
"Her one sword was knocked from her hands, young Loren knew fear for the first time, and vowed to always have a spare."
"She was saved by a man before she was attacked by the low-lifes. That man ... was Saren."
"Loren sat down on the ground in the middle of the forest, finally letting her memories flood her."
I particularly like this one since shows that already when Loren was young, Saren was looking for her, protecting her.
