Voidhelm

A voidhelm is an arcane artifact that allows a ship to exit a planet's atmosphere and travel through wildspace. Without a voidhelm, a ship cannot be expected to make the transition from the Physical Realms to Wildspace. If a vessel's voidhelm is damaged while in Wildspace, it cannot be piloted through the Aethyr Winds, and as a result is subject to its whims. Many vessels that have suffered voidhelm damage in combat have been carried off by the winds, never to be seen or heard from again.

A voidhelm is the key component to a starvessel that allows it to cross the Veil separating Physical Realms and Wildspace. If a vessel attempts to leave a planet's atmosphere without the use of a voidhelm, they face ever increasing resistance as though one were attempting to push two similarly charged magnets together. Eventually the built up tension will stress the hull to the point of failure, destroying the ship and killing its crew. Or the vessel will 'bounce' off the Veil, and be sent hurdling back towards the planet, subject to its gravity.
