I remember quite clearly back in the day there used to be a stable master at the moonglow inn. I may be wrong, but I don't think so. Just an FYI.
The two main shards I played on way back when also had a stable master. No stable, just the npc character standing outside. For what it's worth.
There was a stable master located in front of the Inn in Moonglow across all servers if I am not mistaken, but I believe they were only found at this location in Trammel. If anybody is able to find a picture or some sort of data source proving they existed there on the felucca fact then I will add a stablemaster to Moonglow.
I did some research also and determined you are correct, but I have yet to find out if the tamer was in Felucca or Trammel. Given how OSI treated Trammel/Felucca we can pretty much assume it was trammel only.
