New calendar. Some things to note:
>Heimdallr's sprite was updated which means she's the Mythic at the end of the Month
>Daylight Savings is ending in America on November 2nd
Don't take the November dates on the English calendar at face value because NoA uses Pacific time and reset on the West Coast after Daylight Savings is at 11pm. Look at the "Text of an Axe Quests" at the top of the Calendar. It says 11/1 on the English Calendar but the Japanese calendar it's on 11/2 which means it will actually take place on November 2nd.
>Bound Hero Battle is Fogado and Timerra instead of some Fates combo
Every BHB map released the month after has been some combination of characters from the previous month's game. October getting an Engage BHB is implying that Engage was originally supposed to be the September New Heroes banner before being swapped to Fates at the last minute. The next Engage banner would have to be this month unless IS intends to shill Shadows so Engage is pushed further back to November.
