The game is a fantasy title set in a universe based on Slavic mythology and culture. So GOG included Slavic runes in its email promoting the title, including the Sowilō symbol, which means “sun”. According to one of GOG’s multiple explanations, some platforms, including mobile phones, rendered the rune as ϟ.
Adding confusion to the situation is a statement posted on Reddit by a verified GOG rep saying:
“I also recognize that placing two such runes next to each other could create an unfortunate association with symbols used by the Nazi regime. This was noticed before distribution, and out of respect for local sensitivities, the material was not sent to the German community.”
This has led many users to question why the newsletter was sent out to other localities or why the symbol was even doubled up in the first place.
The developers of the game have also expressed confusion, posting in a Reddit thread that, “We don’t know why GOG used symbols in their newsletter. Really, we were also totally surprised when we saw the logo in the newsletter (the old logo) and the symbols next to the newsletter title.”
