Gazhekwe,
You said "It is said that Michipichu was very angry about this and nothing will appease him. From time to time, he visits trouble on Detroit, and his son, the Red Dwarf, appears in the city to foreshadow the trouble. "

So does Le Nain Rouge cause the trouble, or is he just around when his father causes the trouble?

Do you know of any accounts of trying to keep him from coming or to appease him?
