Kavan had already believed the fact that the guard who was sent to the monster dungeon was actually an illusionist. Since this was an opportunity in saving Fannie, he didn't hesitate and followed after the guard who was heading to the monster dungeon.
After some minutes, the guard paused and turned back, however, Kavan had already predicted his action since he had been walking slowly as if suspecting that he was being trailed. Kavan hid behind the nearest wall and then proceeded in walking behind him when the guard turned back and proceeded in his walking steps.
Some seconds later, the guard stopped at a huge entrance, knowing what it was, Kavan decided to show up himself. He immediately walked to the guard that was about to enter and tried holding his neck, however, as if the guard already knew he was behind, he took out his sword and slashed him at his side which let out a painful groan from him.
