William Fash writes that rulers 8 and 9 reigned only nine years, whereas both Rulers 7 and 10
enjoyed lengthy reigns, and dedicated many monuments.
Ruler 10: Perhaps named "Moon Jaguar", according to David Stuart. This king has a few stela fragments to his credit, and may have been responsible for the bulding of the imposing "Rosalila" structure in the main acropolis.
Ruler 7: B'alam Hehn, "Jaguar Mirror"
