During the wedding festivities in Tarsus Levon could then take the denuded of its defenders castle. He forced Hethum to enter the monastery of Drazark. Lampron, he handed his mother Rita of Barberon, allegedly because he was afraid that any vassal, he enfeoffed with the fortress, would rebel against him, because it was impregnable.
