The young engineer's colleagues knew him as Savva Sokolov. He thought of himself, now, as Silvester Strnard. And whatever name he went by, at the moment he was something else that started with two S's -- scared shitless. To be saddled with the fate of humanity was a heavy burden, and for a naturally nervous man like Silvester/Savva it was enough to turn him into a completely jittery mess. Yet despite the way his trembling hands shook the glass of water he was attempting to cool his nerves with as he looked over his work, he wasn't going to back down.
Until a few years ago, Savva Sokolov had only known life in Salvios, as an engineer of Salvios -- not a particularly prominent one, mind, but secure in his life as a servant of Salvios and surely as native-born to Salvios as it gets. Then he'd been approached with a mysterious letter, taken out to meet another Salviosi engineer and two Abberans, and informed --and made to remember-- a past as a Kolubarian, a Slovene, a proud if-still-kind-of-generally-terrified pan-Slav, and a wizard. He had worked on runes, but his greatest passion had been to work on improvements for the Sky Eye spell, which projected one's consciousness out to a distant point.
Now, after this revelation had shaken his life upside down and given him two separate sets of memories, had seen the normally-meek man go out of his way to push... controversial work, meet with enemies of the Salviosi state, and work with people from outside of the very world itself to try and save it. Now, after these years of frantic preparations, it was all culminating. Silvester found himself drawn to his work all that... time ago? Space ago? He wasn't sure. But the point was that things were deep in the fog of war even for someone who knew as much as he did, and if Harren was going to get through this they needed a coordinated system.
It was blueprint work on a smaller radio that sat on his desk -- and part of him had to acknowledge the irony of that. A real page from the Abbraccian book, it was. And despite the instinctive feeling of distaste that brought him... in retrospect, the enmity of the Abbraccians and Kolubarians really hadn't mattered, had it? They'd been destroyed by Gavros all the same. Taking a page out of their book, then, was only fitting for trying to protect all of Harren.
Glas Boga
The Glas Boga is a radio system designed to beat out the Ceramah in raw power and range significantly through the usage of one of Harren's unique resources. Though the mechanism the radio uses might in fact allow for man-portable versions, this was not the goal of the project: the Glas Boga radio is simply intended to be ship-portable and very powerful. Salviosi engineers had of course already known that Gavrilium was capable of interacting with other objects to create energy seemingly out of nowhere, with the only cost being some of the surrounding area's heat -- after all, the Gavrilium Engine that much of Salvios' forces had run on since near the beginning of the war operated through Gavrilium rods providing kinetic energy to a motor.
I have been attempting during this last year to apply the same sort of concept to radio waves. Whereas the Ceramah radio uses a vacuum wave and antenna to amplify its transmissions, the Glas Boga utilizes a very carefully designed cylinder of very, very thinly cut Gavrilium -- backed by a thin skeleton of other metal, when radio waves pass through the Gavrilium layer, they come out stronger, and the area is made slightly colder. This temperature difference isn't very notable for singular layers of Gavrilium, but the Glas Boga's transmitter antenna is surrounded by multiple layers, which amplify radio signals to be receivable across all of Harren. This makes the area much colder... but since it's a radio, this isn't much of a problem except for the people who have to handle it, and since only the transmitter uses the Gavrilium, as long as it isn't being used continuously this shouldn't present a large operational problem.
The likely problems with this approach are that it creates an apparatus that must be handled gingerly, particularly if ice forms, but it should be worth it for the power of a ship-mountable radio that can transfer to the entire continent.
Operation Sky Eye
This isn't a design but rather a plan of action -- the Glas Boga radios are provided to a network of many Charybdises, St. Maries, St. Thaddeuses, Argos, Neptunes, Nodens, and the Sky Tyrant -- and the former two categories are placed on a patrol network around and over the continent in order to keep as much of the continent analyzed as possible. Whenever any of the ships in the network come across enemy or unknown forces, they use the Glas Boga to inform the entirety of Harren about it on the spot. If the Abberans cooperate, this would also allow the Sky Tyrant to respond far quicker to enemy attack forces.
