The trap was interesting, still exposing oh so many vulnerabilities. For one it showed that the house, as expected, was protected against magic use. But that didn’t really pose a problem for Omega, disabling surveillance like this was easy, not to mention all his spirits were still lurking in the shadows and both of his devices hid him. In the world there are many ways to access the shadow plane, but it’s not easy, even if the mage has the proper knowledge without at least some attunement or contract, one could not connect so easily. Creating or casting a spell to connect to it, or enter it, even if for a little was possible, but calling something from there was not. Fortunately in the world there were many openings where such “gates” naturally formed, however they were they were closed.
Omega found such an opening so why not use it. For the man connecting to the plane of shadows, which some call darkness or death, was like breathing, both because he was attuned to spirits, this is what his past training was good for, but also because of the ‘pact’ he had entered into, one he unknowingly started fulfilling. Still he called on a few little prankster spirits, these ones were a bit different from the souls that normally one would call. While uncontrollable, Omega knew how to influence them. You will cause much mischief if you follow the electricity cables and unlock the surveillance for the portion I’m in and block outside or inside interference. He told them telepathically. They of course would most probably do what he wanted locking the building with only a clear path to his target. Still even if they only pranked what they wanted Omega made sure to send a little additional help.
Still if it didn’t work, he’d just manipulate the electronics to his bidding, after all hacking like this was some of the basics he worked with, so no matter what surveillance he’d be able to crack it. If they did what he wanted, he’d weave a few precautions for the possibility of getting attacked, but if the house was warded preventing him from using magic to get out, he’d assume the same was true for the target, still better safe than sorry. Going about the mansion he was prepared to retaliate at any time, that is until the target would be confronted, he’d either dodge or disable the guards. He was prepared, cautious as to what might happen, or any traps that lurked as he slowly moved about.
