Days that Never Were (Fractured Days Split the Sky)

If you gain a Major Power by non-standard means or from a place other than the Major Power deck, do you have to Forget a card? How about the "gifting" of Entwined Power's threshold or "taking" a Major Power?
"Gifting" is a transfer and does not require Forgetting, and "taking" explicitly doesn't require Forgetting. But for any Gain of a Major Power, you must Forget unless the effect specifically exempts you.
As usual, you may Forget the Major Power you just gained, if you'd prefer that to losing any of your other Power Cards.

When Fractured Days Splits the Sky plays Destiny Unfolds and gains a card from their Destiny, do they also put a card in Days that Never Were?
Yes, and they can usually put any card they could have picked from their Destiny into Days that Never Were; they don't have to pick a Power Card of the same type as the one they gained unless the gain effect had a restriction.
