To be honest, ever since Langit and Edwin became Candrasa's minions, Mekar has been living alone in Langit's dimensional portal more and more. The young girl created a special space inside the dimensional portal that could be connected to Edwin and Mentari's portal, then allowed Mekar to live there.
It was like a dimensional portal space within a dimensional portal space. No one but the three of them knew about it, so if at any time a creature tried to search the dimensions of the three Wrenas, they still wouldn't be able to find Mekar.
But even so far, not a single being has ever entered Wrena's third-dimensional portal. Mekar can always hear voices outside her room, in her friends' dimensional portals. All this time, there had never been a sound that approached her when she was alone.
It's always a safe place.
