This is a Too Old for Neverland story.
Summary: Underhill is nothing without His children.
It’s always twilight out the windows in Neverland.
Inside the halls, it’s sunny summer days, or winter, or fall, or spring– behind every door is another place and time, because everything here is a memory. There’s nothing new and nothing changes, because that’s the tradeoff for living in the heartbeats between Time.
Only Peter’s stolen children can create.
Real things, false things, but always new things.
But that fades, over the centuries that don’t pass. Soon they are discarded for a fresh imagination and without attention from the Fae
Unless Wendy can save them first.
