((Sol did some scrying last night. The following information will be summed up and left on the desks of whoever wants it:
First, on the helmet from the chopper pilot:
The image before your eyes gets clearer: You are in a room filled with chairs facing a podium with a whiteboard behind it. The podium is empty, but most of the chairs around you are filled. People wearing flight suits, combat uniform, some even dress uniforms. All of them wear a blue beret, adorned with a grey wolf with wide open jaws. The lively chatter around you suddenly dies out as a very senior looking officer steps into the room and walks up to the podium.
You focus, floating in outer space, as slowly your view "zooms" in.....The Atlantic....America...Solomon Island. A massive tanker is gently swaying in the waves off the coast near Kingsmouth - far enough out and away from the fog.
The tanker itself seems to have been repurposed and heavily modified. Fastened on it's deck are three helicopters standing on what can be best described as makeshift helipads - large metal plates welded to the deck of the ship. No flag, not even the signal ones, are displayed. The only hint at the ships origins and identity is a large, white lettering on the ship's portside aft: "Maria Teresia"
You manage to memorise the ship's coordinates, however, since you wanted to be very precise and kept the ship in focus for quite some time to ensure that precision, you witness the following: A dark shadow, down under the water, approaches the ship from starboard. It vanishes under the ships bow, but doesn't emerge on the other side again. The ship sails on, cutting through the ocean waves as suddenly its mid-section seems to be lifted out of the water, creaking loudly before breaking apart. The ship, now with it's neck broken, turns onto the side and slowly sinks.
[Arnbjorn]: You focus on the shadow just as it is about to vanish under the bow. Your focus is aided by Sallah and your view "zooms" in again, breaking through the water and revealing what's under it - a long tubular shape, slowly losing the momentum it had while travelling through the water towards the ship. It stops and slowly starts to drift upwards to the surface, only to hit the mid-section of the ship. There is a loud "thud" as it bounces against the hull. A few seconds later your vision is filled with a mess of bubbles and swirling vortexes of water as you can feel an immense heat and shockwave rippling through your body.
You zoom in on the object and there seems to be lettering on it as well: G7e "Lerche"
TL;DR: the helicopters were launched from an offshore tanker which was retrofitted to carry them. The tanker's name was "Maria Teresia". After withdrawing from the coast of Solomon Island, it was sunk by ordinance bearing the name/designation "G7e 'Lerche'"==============================
He scried using the copy of Vik's 'soul' he collected in the tunnel.
You follow the trail, zooming and zooming. You submerge, floating deep down the ocean, entering solid ground in the depths below. Like a drill you make your way deeper and deeper, the ocassional fossil of something that you've never seen before blocking your way, only to be drilled right through. You are no archeologist, you do not have time to stop and examine. The journey down seems to take forever, but finally the ground cracks open and you are engulfed by golden light as a familiar view graces your eyes - Agartha.
Having arrived in Agartha you come to a strange realisation - the signal can not be pinpointed. It is all around, flowing with the streams of anima that traverse the world tree. There are moments when you feel like "Vik" is more in one place than all the others, but those are far and few between on top of being inconsistent. Ultimately, the signal is scattered.
TL;DR: Vik's essence has been absorbed into agartha, and does not reside in a single spot. Sol is brainstorming a way to try and get it out.================================
Finally, he tried to find the Thule Society's headquarters
Your vision goes black and remains that way for what seems to be ages. Once it clears again you are standing on the roof of a building, overlooking endless wastes of snow and ice. The snow is gently falling down on you while the cold wind sends a chill down your spine. Looking right over the edge of the building you can see the flags adorning it's front - a black cross on red ground with a strange circle in the middle. As you survey your surroundings you suddenly hear a voice from behind you. "Halt! Wer zum Teufel sind sie und was tun sie hier?!"
You are in the process of turning around, in slow motion. The entire building seems excessively warded to avoid both prying eyes and curious visitors. Whatever may dwell inside - you do not manage to pick up any hints through the wards. Just as you finish your turn to look at the voice you stare into the barrel of a gun, two red lenses glaring at you. (http://neokerberos.free.fr/imagespg/accueil.jpg)
The soldier takes a step back as Solomon erects the shield, letting loose a burst of machine pistol fire. Unluckily for Solomon, the shots pass right through his shield, but then again, luckily for Solomon, the shots also pass right through him without doing any damage. The soldier stands there for the fraction of a second, taken by surprise, amazed. You can hear the faint crackling noise of a radio, followed by a loudly shouted "ALAAAARM!!"
Also, another vision:
