After taking care of his many affairs.
Soren prepared to set out for Arendelle. To deal with the Lord of Shadows, he needed the Princess's help. He had long suspected that she had inherited the bloodline of the [Goddess of North Wind and Ice and Snow], but he had no definite information to confirm it yet. The Winter Maiden had yet to appear, and the Princess would only face real danger during the "Snow and Ice Riot," which came in the middle to late stages of the Time of Troubles. Bringing the Princess onto his side now would benefit them both, since she was constantly growing stronger through her battles with other deities.
As it happened.
Soren's sudden decision to strike at the Lord of Shadows had been prompted by something else.
The story went back a few days.
Soren had ventured into the God's Realm of Malar, the God of Hunt. It had been an exceptionally rewarding expedition: not only had he gained considerable divine rank and divine power value, he had also accumulated over two million slaughter experience. Originally, he had planned to leave after exploring part of the realm, because the second wave of the Time of Troubles was about to begin. But he could not bear to give up such rich rewards. The God of Hunt's realm was collapsing ever faster. If he left now, it would probably be destroyed by the time he returned.
So, in the end, he decided to wander around a little longer with the Lady of Silver Moon's avatar.
Even without any other gains, the slaughter experience and divine rank alone were worth spending some time here. Besides, he had already made extensive preparations in Port Nyanzaru. Even without Soren there, the city should be able to weather this crisis safely.
