Dear Nadia
Dear Nadia is one of the Documents in Baba Yaga: The Temple of the Witch (additional content for Rise of the Tomb Raider). It belongs to the Grandfather's Journal set, with written notes from Ivan to Nadia. These tell of Ivan's stay in the gulag, the birth of his and Serafima's child, and the will to do something more in favor of the innocent prisoners.
You deserve to know the truth, to know why. Your Grandpa is not a wise man. I have become, with hard work, a good man, for your Grandmother's sake. But it was not always so.
I came from the West, where even a small village has thousands of inhabitants. I was a lazy young man, and I dreamed of an easy life when I joined the Party, a comfortable desk in the big city. But they sent me here, to the ends of the earth. To watch mean and women work and starve and die. To participate in their punishment.
I knew it was evil. But I did not know how to fight. Until I met her.
