Hello @cryptofi,
Stories about brothers have great value as metaphors. If we look at the Christian religious tradition, for example, we have Cain and Abel, Joseph and his twelve brothers. These stories are meant to instruct us, morally, and so yours does. It is the younger brother, through forgiveness, generosity and kindness, who saves the older brother.

This is a good story. Gentle proofreading would make it even better. Little errors such this one:

until he to ancient magic tree

interfere with the reader's enjoyment of your fine story. You probably meant so say something like this: until he came to an ancient, magic tree.

You see how that reads better?

You did a great job. I look forward to reading more of your thoughtful stories.
