Does anyone remember (agricultural) TVO?

Does anyone remember the name of these two board games?

• I remember having this board games as a kid (which would be in the 80s/90s). I was trying to remember the name of it so I can research/buy it but I only have vague memories of playing. I hope by giving some info someone can help me remember the names of these two games. It was a fantasy based board game but if it helps it was not based on Hero's Quest or Dungeons & Dragons: It had a board that you built some sort of stairs on that reached upwards. They sort of curved around the left side of the board and stopped over the tower/castle/keep. I think the goal of the game was to get your character up the stairs. I also remember a large castle that you could put your figure in and hit a lever/button that would change it into another figure (via some sort of revolving mechanism I'm sure). I think I remember a dragon being one of the figures, but I don't remember any of the others. There may or may not have been owning pieces of land (similar to risk, maybe?) involved as well but its been a long time since I've even thought of it. I may only be thinking that because I remember it had some sort of map involved...but I think there were some sort of "properties" on the map. I've looked online and know its not the one called Dark Tower. I think if anyone would recognize this game the defining features would be the keep that allowed you to change your character into something different and the stairs. You get tons of awesome bonus points if you can figure this out, because I've found a couple of other old games I was trying to remember online but not this one!
