Just past the Palace of the Initial Series is Palace Diablo.  An amazing stela stands in front of Palace Diablo.  I loved it.  I do not recall feeling anything about the Palace.

According to the INAH Plaque accompanying this temple, archaeologists called this temple the Palace Diablo because of the anthropomorphic column representing a skeleton type person with 2 openings in the upper part of its head in front of the principal facade.  3 rooms compose this palace: a front room, a back room, and a side room flanking the 1st 2 rooms on the east side.  The Mayans built this palace during the Terminal Classic Period (750 - 1050 A.D.).
