Pepe LeRat is the new Lord Hendrake
Pepe LeRat is Louis LeRat's younger brother. He is the head of the most powerful House of Chaos and owes that position to Lord Kiron. Who knows what he will do if Lord Kiron never returns from his trip to Amber. It is said that Lord Hendrake has a document detailing most of what Lord Kiron knew before his disappearance, but it is hard to say whether this is true or not.
Drawing this Trump in a spread indicates doom.
