Clue of them

"Then what should we do now?" asked Alyura.

"They're all not here, and you don't feel their presence here either. That means they're already far away, so how can we contact them and look for other people who have also left this palace?"

 "Let's use an easier way, try calling one of them using your cell phone," Lucas said.

 "I don't have a cellphone, after I was kidnapped and I entered that magical dimension, I lost my cellphone during a natural disaster that occurred in that magical dimension," said Alyuura, she did take her cell phone when she was sucked into that dimension but between some time in there everything was lost because of the storm that hit him hard.

 Those who had taken Lucas' cell phone in the palace then used it to contact Damian and Yaris, not only the two of them but they were trying to contact people they could contact.
