Psionic Helms

Long ago, in the mists of Ancient time, someone mentioned psionic
helms.
I'm working on an extension to SpellJammer (to be called Future
Realms) which will involve the Fall of Magic (and spelljamming).
Psionics will take hold and become the ruling power.  Anyway, back to
SpellJammer - there is a psionic power called Dimension Door, and
this power allows travel across reasonably large distances in reduced
time, using the astral plane (or some such thing).  I don't believe
that a normal psionicist could conceivably power a ship up to full
SpellJamming speeds, so I have created a helm which opens a Gateway.
This Gateway leads into Chaos Space, a realm where time and distance
are distorted.  It would take an amount of power dependant on the
tonnage of the ship to open a large enough Gateway.  Also, since the
ship could not be pulled back to combat speed as in SpellJamming,
instead objects in normal space create an 'attraction' to ships in Chaos space, and
thus they are 'pulled' back through as per the normal rules.  Another
thing would be that ships could encounter one another in Chaos space.
This would solve the problem of too many PSPs being needed.  I have
also made an adaptation for SpellJammer - a creature called the
'SpaceJammer' (I call this method of travel SpaceJamming) creates the
psionic effect as a natural ability, and the creature is controlled
tightly by one or two mages.  This is sketchy - I haven't developed
it yet.  If anyone has any suggestions or can find anything wrong
with this idea, please reply, and feel free to use it for your own
campaigns.

Thus without the SpellJammer the universe could not exist.
