The Tunguska Event was a massive explosion that took place in Siberia on June 8, 1908.


In Werewolf: the Apocalypse continuity, the explosion occurred because the Zmei Trevero broke free from the Rite of Draconic Binding, and the resulting battle with Uktena, Silver Fangs, and a Dreamspeaker mage resulted in the explosion. [1]

A completely alternate explanation for this event comes from Mage: the Ascension canon: the explosion was caused by Void Engineers crew trying to investigate curious alien ship, dubbed ‘The Vivo’ by them, and accidentally causing it to generate miniature black hole. [2]
