The people to arrive were 3 different groups.
The Fantastic 4 were exploring an underwater location that held some creatures never before seen when they saw the explosion from a distance. They boarded their ship to fly over and see what was going on.
The second group was doctor strange and his apprentice/wife Clea. Dr. Strange sensed a large amount of magical energy gathering when Jason was preparing the Noble Phantasm so he teleported over as soon as he could, especially after he felt the large release of magical energy when the explosion occurred.
The last to arrive and with a bolt of lightning as their ride was Thor. Thor did not actually sense the explosion itself but felt the release of divine energy in the area and came to investigate. Only when he arrived did he truly understand that the god that caused that damage was very powerful.
"So what exactly happened here?" The Human Torch/ Johnny asked others to arrive since he was very confused. He could even feel hot from the heat so he knew that it must have been something supernatural in nature.
"I would say a powerful magic-user has surfaced. As for whether they had just awakened and were testing their powers or they had encountered danger and were defending themselves, it is impossible to know at the moment," Clea replied.
"This was no mortal magic-user. I can feel divine energy in the area that originated from that attack. Whatever was involved here is related to gods I do not recognize," said Thor
The members of the Fantastic 4 looked very puzzled and confused. Although they had worked with other heroes and dealt with magical or godly enemies, they were still scientists at their core and found things such as this hard to believe.
The group began to investigate but even under the combined forces of all 3, they were unable to come up with any clues about what happened exactly or who did it.
After a few hours, this became a mystery that got the attention of many governments who were throwing blame at each other or blaming certain races, groups, or organizations. Many terrorist organizations tried to claim credit for the move but none were believable.
No one knew that the true perpetrator was in the North Pole and about to create another mess there.
--A few hours back and in the North Pole--
Jason and his group had arrived safely without anyone finding out that he was the 'divine terrorist'.
He had shifted to his human form along the way. Jason recalled both Anastasia and Dr. Jekyll before sending Achilles away. He wanted to have a private talk with one of his Servants.
After Achilles left, he was all alone in the frozen north but he was not worried. He pulled out a golden card before crushing it.
The figure that appeared in front of him was a blonde, Aztec goddess. She had a jewel in her chin that was the same emerald color as her eyes. She wore modern yet ancient Aztec clothing although her poncho was short and barely covered her chest. The woman was also not wearing a bra underneath so if she moved too much, she would flash anyone who saw.
The two parts that stood out most about her were her smile and aura (although those other two things really stand out as well). She had a small yet bright smile on her face that would make one think of the sun rising in the sky. Her aura was warm and enveloping for anyone in her presence like a true goddess of the sun.
This woman was the Avenger Servant, Quetzalcoatl. She was the goddess of peace, knowledge, war, the morning star/Venus (love, sex, and beauty are the common associations with this), goodness, wind, and the sun. She was considered a chief god, like Odin or Zeus, and could rule over an entire pantheon.
This was the Servant that Jason never wished to battle. No matter what other Servants he faced, he knew that if he used any other pair of Servants with him, he could beat them. But Quetzalcoatl was a monster in a human's (Servant? Goddess?) body. She even had a skill where she could learn any skills she wanted or bless others with those skills yet did not for whatever reason was going on in her mind.
And this was all of her while she was weakened and not fully ascended. What she would be like after she ascended, even Jason did not want to see what wrath she could unleash as such.
But Jason did not summon her for combat training or for skills. He was trained by those who were better with weapons. He knew that having skills that were not suitable for him was more of a burden than a help.
"Oh my! Little Master! You seem to have grown much more powerful since I have last seen you. I even sense some divinity inside of you as well as a Saint's Graph."
The woman jumped in front of Jason before he could even react, even with his instinct, and began feeling up his body as if confirming all the changes she mentioned.
"Hmm. I definitely feel some divinity. You have a large amount of dragon blood in you. YOu might even be able to turn into something comparable to me later.
I can also sense divinity of a few types within you. One is similar to one of mine. Yep. I sense the sun within you.
You also have quite a few divine constructs that are now yours. Hmm. Interesting."
Quetzalcoatl continued to talk and check over Jason's body for over 10 minutes before she backed away and was satisfied. Jason was sure that she knew more about his body than he did.
