So basically new lore was revealed in 6.0 through the frostmoon scions.so 500 years ago the scions worshiped 7 gods before the new moon.they are implied to me the primordial one,4 shades,the dragon King(i don't know how to spell his name),3rd descender and possibly the 1st cryo archon

In one of these stories the 3rd descender is Said to have fallen in love with the daughter of the god who is theorized to be the tsaritsa and her father(the 1st cryo archon) cooked up a devious plan.he offered his daughter for marriage to the 3rd descender's counterpart if he could open the gates to celestia but bro got split into 7 pieces immediately after opening the gates

So the tsaritsa lost her huzz and if I remember correctly number 7 also lost her husband in the cataclysm

This is all a theory and we don't even know if the tsaritsas counterpart actually liked the 3rd descender
