Since it's the very first stage and it's built as new players can get into the game mechanic, I don't want to overly dump information which players may feel the game is too difficult.
I'll consider your gameplay for the later stages.
Although you could make a level that teaches players the mechanics of the game, for example, a level where the village where Nesche lived was attacked by orcs and she had to hide, while trying to escape, but eventually she would be noticed, captured and made a slave, at the same time show how Nesche became a slave and let new players get acquainted with the game mechanics before the start of the game itself, and the title of the level itself would be an introduction or something similar, also make a function in the gameplay settings that turns off the training, because I'm tired of seeing this training every time.
