The scene that Felix arrived to see was quite chaotic. A gigantic gate of light was being opened near the ceiling of the underground area. Altraeimo's shivering form was dancing in front of the gate. He was blowing his flute to continue the opening and stabilization of it.
Felix's appearance didn't surprise Altraeimo in the slightest as he continued his dance while sending Felix a telepathic message:
"As you can see, you came a little bit too early, but I can't blame you. The commotion that happens when opening the gate is quite immense."
Felix could sense that. The earthquake that he felt when Altraeimo started even moved him a bit.
This showed that the opening between dimensions could injure Altraeimo if he didn't do it properly, so Felix wanted to make sure nothing happened to him.
If something happened to Altraeimo, his only chance of getting rid of this damn Lotus on his forehead would disappear until he died of old age.
