Maria 'Inverno' Gunina, former Strategy Director at 9Pandas, noted on her personal Telegram channel that the locations in "Fallen Crown" resemble the setting of Diablo 3.
She pointed out that Dota 2 appears to have borrowed from Diablo 3: the first act is set in a temperate region, the second in a desert, the third in icy terrain, and the fourth, presumably, in some celestial realm.
Earlier, Gunina also commented on the conflict between Edgar '9Class' Naltakyan and Dmitry 'Fishman' Polischuk.
