One after another, Karyk kept devouring the Titans in other rooms. Some were unprepared and easy to kill, while others fought back, only to be killed by the large number of undead titans that served Karyk.
There were also many rooms that were completely empty as the people residing in those rooms had not returned from outside. Karyk left a few Undead Titans near those rooms to wait for the person to return and be killed.
It all happened so silently that not a single person outside of those rooms had a clue about it. Within the night, the entire mansion was filled with Karyk's undead.
Throughout the mansion, Karyk only came across the Titan Warriors, which were the lowest ranked. He didn't see any Titan Mage or Magic Warriors as those with higher positions were allowed to stay at a different place.
