Alright, for the next lesson, I want to give you a little bit more practice on dialogue, but then I'll do something else too.
In this lesson, have Issac follow Valin through the Dome, and have Issac inquire about Valin's origin. This conversation should not be short--not obscenely long, but not short either. During the conversation, have Issac lose Valin in the hustle and bustle of the Dome. Without a guide, Issac will find his way to the Creature Grounds. Do
not merely state that "Issac found his way to the Creature Grounds." Explain how he gets lost, explain his thoughts, describe describe describe the environment, anything and everything you can think of.
The Creature Grounds are a massive savanna with a few stray trees (essentially any picturesque image of an African plain

). Issac will enter, and wander for a bit, but will soon come across a higher tree. From this tree, he will hear someone say "Hello there." End the post there.
We're getting there, man! Keep it up, you're doing really well.
