Just past the Palace of the Lunar Series is the Palace of the Initial Series.  I do not recall anything about this temple.

According to the INAH Plaque accompanying this temple, the Palace of the Initial Series got its name from sculptured lintels with hieroglyphic motifs that archaeologists found in entrances 7 and 10.  The Mayans also built the Palace of the Initial Series in the Proto-Puuc architectural style.  However, the hieroglyphic inscriptions deciphered on the lintel of entrance 7 indicate a date of 487 A.D., which corresponds to an earlier architectural phase called Early Oxkintok, extending from 300 to 500 A.D.
