Planting little by little the seeds for the halt and theatrical search in the stars.
They leave clues and notions that will lead the younger brother to invent
things in secret, small flying toys and marvels of artistic ingenuity.
The sister always keeping him safe and out of harm of being discovered.
Years pass and its close to ceremony of the wheel,
where the children will take over from there mother and father.
The younger brother has now created two small hemisphere bobsleds,
generating static shielding to fly around with.
He convinces his sister to take a last ride before taking on responsibility.
The now very old butler and nanny makes there move re-programming
the sleds to crash in the outer rim among the worker tinkers.

This journey will take them trough exploring there reality,
them self and mostly the love for the genuine artistic tinker people.

As the iconics does not know anything else, gets persuaded  to
stop at the now close planet, be co-workers and learners
along side the tinkers, setting foot on the new frontier.
