Dark witches coven
"my lord the child can not be found, we've tried tracking her with a location spell and it seems like she disappeared from the earth surface" one of the masked men in black said bowing in front of the dark lord. He has his hand supporting his head as he stared around the room saying nothing, and the masked man took it as a cue to continue.
"the news said their plane passed through the trajectory of the Bermuda triangle. No plane and no one has ever survived it, thus bringing us to the conclusion that she is dead." he concluded with his head still looking down.
"the child is not dead I can feel her but its faint meaning she is on the brink of death." the dark lord said calmly. His calm tone brought a relief to everyone's heart, knowing no one will be dying that day.
"everyone leave, except you" he said pointing to a man with a red mask. Everybody left the hall feeling remorseful towards the man.
"my lord" the man bowed after the door has been closed behind the last person.
"I'm listening" the dark lord said.
"your intuition is right, the child is still alive. Her mother does not look like one who just lost a child" the man answered.
"okay, its not like they will be able to escape the force of the triangle . They will stay there for ages that's if they can survive in the wild. They can not return and I will be king of all supernaturals." he said with a cackle and an evil glint in his eyes.
Somewhere unknown
"the dark lord shall be king over all supernaturals, doom has befallen the earth. But wait what is this I see?? There's still a glimmer of hope for mankind, the dark lord shall be killed by his own kin. When that will happen, the stars can not say" the strange woman said as she gazed at the stars.
Unknown location
The place looks like a small estate with few houses. There's a training court, a basketball court, a small hospital, a section for archery, its own garden with different types of food, three storages for keeping food and other stuffs. In the middle of everything stood a rather big mansion of six floors, which covered a lot of space on the estate. Everyone on the estate stays inside the building. It's owned by Grace,(your guess is correct it is inside the Bermuda triangle)
Grace found this place years ago, she mistakenly stumbled on a passageway that led to the mystical place on one of her vacations.
On arriving there, there were about 20 survivors including children who seemed to have been born there. Since she is rich she was able to build there, though she tried taking them out but it seemed like the passageway will only acknowledge her. How she got the materials to build is still a mystery to the survivors, well being a witch has its perks but the people also helped especially with the garden. Everything inside is of recent technology with all sorts of solar technology to power up the place. She was also able to get them all sorts of clothes, materials and things needed for sewing. Since it was not the real world, the hospital although equipped with everything it needs for the sick, Grace was able to get three doctors who were willing to leave their lives behind and stay in the triangle. It was easy to convince them since they have no family and friends back in the real world.
When the dark lord rose, Grace knew the only place Linette could be safe was in the triangle, and since no one in the world knew about the secret passageway and no one could enter there without her inviting them, she knew she could train the little one there. Thus she came up with the plan of a disappearing plane in the middle of the ocean.
Mind you they never boarded the plane
