In Changeling the Lost: Second Edition, it is said that a Huntsman’s heart resides within a Bastion. It even specifies that
the heart can found within the tempestuous mortal Bastion
So, the Bastion is one of a mortal dreamer. It is also said that
A Bastion only exists for the span of a single dream. When the dreamer wakes, whether naturally or because a paradigm shift jarred them awake, the Bastion crumbles and disappears
What happens when the Bastion containing the Huntsman’s heart crumbles? Does it destroy the heart, which implies that a Huntsman only exist for the span of a single dream? That would seem to contradict the "Wild Hunt" paragraph
so long as their heart beats in their stolen Bastion, they reform somewhere in the Hedge within a month’s time to start again. And even when the heart itself is destroyed and the Huntsman is no more, the animating Title’s fire flits back to the Keeper whence it came
It seems clear that the designers intended for the Huntsman’s existence to last longer than a dream, but the rules don’t seem to support that.
Does the True Fae move the heart to a different Bastion every night? That would seem very… tedious to do for one of the Gentry. It doesn’t really make sense to me.
So, how can a Huntsman exist for longer than a single dream?
