Of course he is

After you finish your report it stays quite for a while, looking up at your master you are afraid you displeased him, as you open your mouth to apologize a loud deafening laugh fills the room. Your master is actually laughing! It continues for about five minutes before he calms down. When he speaks you hear amusement in his voice: "So you are telling me i send you out to weaken this foolish group of so called heroes and you ended up taking them out single handed?" Clearing your throat you reply"ehm yes Master". "If this is how you handle your first mission i am looking forward to how you handle the rest". Uldar who had been quite until now speaks up "He only managed to do that because of my help Master!" Looking at the cloaked one you growl, "You did not help me in any way.... midget" which he replies to with "No? Then who's voice is it that keeps telling you what is what and where you need to go hm?"Interrupting the squabble your master raises his voice"Yes you helped Uldar, but the planning and execution of the plan where made by him... Make no mistake Uldar you are wise, but you have the tactical insight of a rock."that last comment makes you grin

"Many things need doing my minion, but not today. Today you shall see how generous i am to those that please me. You have slain five heroes, one was injured but a hero nonetheless, so i shall grant you 5 rewards today, impress me again and more shall follow" You hastily reply: "Thank you oh generous master!" "First things first, when you are not doing my bidding you need a place to stay." a key materializes in Masters hand "Seeing as you have no trouble with height i hereby grant you the top floors of the eastern tower, there you will find your room furnished to your needs and a treasure room it is empty now but with some more missions it will fill up in no time.
Secondly i grant you the use of two holding cells situated in the dungeon below the eastern tower" "Why the cells master?" you ask surprised. "Who knows you might catch a hero alive next time and want to play with her" You could have swore you saw your master wink as he said that.
"Your third reward will be a teacher of your choice, no i do not need a reply right away think about it first, there are hundreds of skills you can learn."
"And the last two rewards come together, i now know what you can do on your own, so i am granting you command over a squad of troops, and also their leader. The leader of your chosen squad shall be the first of your conquests...." "Excuse me master? Not that i am objecting but can i make up from this that you want me to have my own harem?" "You have a part of my power in you my minion, if you where to breed and procreate your children would to have a part of my power, creating a new army of stronger, more powerful minions for me. And it is not like i am telling you to **** her, win her over in your own way and try to have some fun while you are doing it. Now chose! Who shall be the first of your wives and with her what troops shall you first command?"

in your mind a list forms of woman, and the squads they command
