Grischa lives in the town of Kashin, in western Russia. He often frequents a local bar, where he gets free drinks by challenging strangers to drinking contests which they have no hope of winning. He does not have a reason to reside in Kashin specifically; any town in russia will do, and if need be he will move towns every ten years or so. He will generally attemtp to keep away from any settlement which presents a high concentration of communists. He does not reside in a building, as he does not have the funds to afford one, and instead lives in the sewers of the city, hidden from prying eyes: his unusual appearance warrants such secrecy.
Money is scarce and hard to come by for Grischa; he mostly earns what he can by making, and consequently winning, bets with anyone who might be unaware of his unnaturally high physical strength. He also scavenges what he can: lost wallets, dropped coins and/or bills, et cetera. Consequently, he only spends money when it's absolutely necessary, and only on essential goods: for example, food and water (in the event that he cannot find alternative ways to gather them), or clothing, especially when the winter is approaching. Russian winters are, after all, known to be extremely harsh, even to the hardiest of people.
Grischa was never one attached to sentimental values, nor to notions of an intrinsic value to human life. However, he was attached to one thing in particuar: tradition. Ever since he's been born, the importance of tradition has taken center stage in his life, from his childhood, to his family environment, to his education and to the war. That's precisely why witnessing the Russian Revolution in 1918 made his blood boil; he seeks to bring down Communism once and for all and re-establish a new capitalistic-industial society based on the values of early 20th century Russia. He has been a silent spectator to the rise and fall of figures such as Lenin and Stalin and yet, even beyond the fall of the Soviet Union, he knows vestiges of the Communist movement remain, and he is determined to prune them. However he is not stupid, and knows that a brute strength approach will likely get him killed: he is biding his time, waiting to gain powerful connections.
The day is the 6th of August 1915. The german forces have been laying siege to the fortress of Osowiec in north-eastern Poland since the first days of July. They wait until 4:00 AM, when the wind favors an artillery bombardment of chlorine gas. The gas rendered the grass black and the leaves yellow; birds, frogs, insects and other dead animals laid dead all around. It was hell on earth.
Many succumbed to this gas... and so did Grischa, who was a medic stationed at the fortress. However, the will to survive in him, and a handful of others, was strong that day. Be it because of a conjunction in the stars or some other occult phenomenon, the dead rose from their graves. The 7000 german soldiers marched onto the fortress, expecing little resistance. They were sorely mistaken.
Zharad Khuznetsov: Zharad was a fellow soldier stationed in Osowiec. He was the scout, an unofficial position appointed by himself, but he was better than most at what he did. The hardships of the first world war fostered a strong sense of camaraderie among the two, as did the fact that Grischa was the sole medic stationed in the fortress and was therefore responsible for operating Zharad's wounds.
Lieutenant Osipov: Osipov was a stern man, with seemingly nothing to lose. Being Leuitenant came naturally to him, leading on the front even more so. Not an exceptional combatant by any means, he found his strength in his aptitude for leadership and his charisma. Under him, the most cowardly of soldiers could face the horrors of war without batting an eye.
Alina Sokolova: Alina was Grischa's wife, though their marriage had been arranged by their families. He spent little time with her before the war, and does not remember much of her.
