Fiction:Wental Transgate System

The Wental Transgate System is a complex network of large gates. These gates could allow immediate travel from any gate to any point in Wental. While they can not send people beyond the Galaxy's borders, they can send people anywhere within those borders.

Each Transgate is approximately 30 thousand miles in diameter, massive on any scale of construction, and made of some of the heaviest and most durable materials in the known universe. Who had made them was unknown, but they were there and usable. The Gates themselves are simple rings, with a concave back to them that is solid. This back is made of the same material as the rings, but when a gate is open the back cannot be seen from the entrance. It's really quite an amazing thing to see, a massive lens like structure suddenly turning into the empty void of space. When you enter one of these Transgates, you can move as far as you want in any direction, just place in the coordinates and you will arrive there. These gateways allowed some ancient empire to travel and, assumedly, rule all of Wental. Now they allow the new empires to attempt to do the same.

Mechanics of a Gate
As far as has been discovered, the workings of a Transgate are simple. The energy comes from the ring, which contains trillions of strange reactors or generators, and is blasted across the entire ring. Like a bubble, it takes on a semi-solid form, but only for an instant. Then it reaches out to the location you have chosen and starts to send matter there. Any matter, regardless of size, that passes through the gate will be sent to the destination. Those entering can't even seem to tell the different, to them they are merely moving through a ring into empty space, but those watching see the ships disappearing as they enter the energy field. It is not entirely known why that happens.

Once you have passed through such a gate, you cannot go back. It's a one way trip, there is no Transgate at the other side to take you back (unless you placed one or chose a spot near one) so if you end up in the middle of an enemy attack your stuck there. You cannot return, but they never fail to send you to the destination.
