You made an account (and with a fitting name no less!) just to share that bit of insight with the world? Talk about dedication...
Anyway, I think what you found out was also already implied pretty heavily in the game itself. If I remember correctly, you find a note in the Archives, basically saying that the human servants aren't working to Alexander's satisfaction and that he would be solving two problems at once if he would give them the wine to drink. (= creating more efficient servants and getting rid of the men the town's sheriff is looking for at the same time.)
The fact that Gatherers are also mentioned in old stories and folklore can easily be explained if one considers that Alexander has been living there for quite some time and probably created quite a lot of servants during his stay. (Nothing indicates that they can also live/function forever. They probably rot away after a while...)
