The situation the kids were in was in no way unimportant to Omega. After all he got to observe the kids not to mention his past influenced him to not allow any more of his kind to be created. Thus he decided to act, though in a way he wouldn't be detected. One thing you should know about Omega is that once he sets out to do something he does the task as fast and stealthily as possible. 

The man, currently residing in Ascot's shadow, frowned. He could easily just pul the children into his realm the drop them off onto the ship. The only problem with that approach was the questions that undoubtedly would be asked, but first and foremost their young minds would get warped if they got pulled into where he resided. The realm of spirits leaves an impression no matter how powerful someone is. 

He shook his head. No he had more indirect approach he could use. He left the task of guarding the young ones to his familiars, while he would message some kind need to the others. The thing now was to get it, that though would be less of a problem, even with the interference within the facility they were held in. 

Both Kaena and Sanu agreed to take this task and departed. Fortunately they didn’t need any explanations due to the connection between the three of them. Passing as normal animals As they infiltrated the compound was relatively easy for the duo. Not only were they stealthy but also they could easily deceive humans due to their ability to use magic, not to mention Omega equipped them with mana crystals and magic stealth devices. 

The two familiars would go to where the kids were held and join them. Keeping them safe from harm, after all they were able to fight and decide the humans planning to get there with fate and other magics they could use. To the kids they'd relay Omega's message. "I'm a friend, the others will come for you soon, my familiars will protect you so don't be alarmed." 

The magic interference in the facility was problematic and caused by makes rather than machines, this Omega was sure of. There were at least two or three mages, not to mention the spirits were restless, meaning that a necromancer was on the premises or at least not too long ago. 

Once Omega compiled the information on the facility, the children and the enemy he sent it to the ship. Of course he would mention he's keeping an eye on the kids and would advise a direct approach but to be careful. He used one of the lines prepared just for passing information so they should accept it. Not to mention the systems they used were really familiar to him.
