Ruler 8 was the last of the successful warrior kings of Toniná . He celebrated a series of events between 789 and 806 , including the defeat of Pomoy in 789 , and the capture of the ruler Ucha 'an Aj Chih , who appear to have been the vassal of B 'olon K 'awiil of Calakmul . In 799 he rededicated the tomb of Ruler 1 . Ruler 8 oversaw an extensive remodelling of the upper levels of the Acropolis . Ruler 8 erected a number of sculptures of bound prisoners of war and adopted the title aj b 'olon b 'aak , " He of Many Captives " . However , the lesser extent of Toniná 's power is evident from its victory over the site of Sak Tz 'i ' ( White Dog ) , an important city in the Lacandon region , an area which had once been dominated by Toniná .
