Welcome to the forum adriennelisa. To figure out the quests with just one Hero, click
here to go to Carl's Sims Medieval Guide.
All quests are listed in alphabetical order. You just click on the quest link and it will open to show you who and/or how many Heroes are needed to complete the different approachs and the quest.
For instance, the first quest 'A Missing Child' shows that you only need one Hero and it can be any of the Heroes you currently have in your game.
The other way would be to check the quests out in-game by clicking on the Quest List button. You can then browse through the quests available at that particular spot in the game. A Quest will not become active until actually chosen by you.
