As Iria's only purpose when she left the palace was seeing the doctor, she only brought Elian and the soldier who drove the carriage. Besides, she didn't want the royal guards to know that she was seeing a doctor.
When Arin became the King, Antony became the Captain of the Royal Guards and Elian was the Vice-Captain. They were the two guards whom Arin trusted the most and it was why he assigned Elian to be responsible for her safety.
The soldier who came with them remained to watch the horses and the carriage. As such, Iria entered the forest with Elian and cautiously made their way towards the abandoned house.
The house was only half an hour walk from the beginning of the forest and the two could see the house in no time.
"Let's be careful," Iria said to Elian. "We will just look around and if we see any clue, I will send the soldiers here when we return to the palace."
