 ==Interstellar Travel==
 The distances between stars is very great compared with interplanetary travel. Although both reaction drives or reactionless drives could allow a ship to travel between star systems, it most cases it would take many decades or even centuries just to reach the nearest neighboring star. For this reason, the advanced technologies of Hyperspace and Star Portals are the only efficient means of traveling between the stars.
-* '''Hyperspace''': An advanced field generator can create a “punch” from normal space into “non-space”, similar to a wormhole, but without a set end point. Effectively, hyperspace travel is like crunching space up like an accordion and traveling straight down the shortened corridor in the middle. The higher the shaceship’s velocity before “punching”, the more crunched normal space gets, so the key to short trips is first getting up to a high velocity using an interplanetary drive before initiating the hyperspace field. WARNING: Hyperspace is straight-line travel. Attempting to maneuver or turn in a hyperspace corridor most likely will result in a fissionable disintegration of the ship.
+* '''Hyperdrive''': Using an advanced field generator, a ship can “punch” from normal-space through hyperspace, referred to as a hypershunt, creating a tunnel similar to a wormhole, but with temporary end points. This is not instantaneous travel however. A period of time, relative to the distance traveled through hyperspace, must still be passed. This transit interval is independent of the ship's velocity when entering the shunt. Changes in velocity cannot be made while in the hypershunt, so the ship will exit at the same velocity that it entered. WARNING: A hypershunt is a straight-line of travel. Attempting to maneuver while in a hypershunt will most likely will result in a fissionable disintegration of the ship.
 * '''Star Portal''': This advanced technology, makes use of the very rare mineral Xylite combined with a huge amount of energy to generate a gateway which connects two points in space. Travel through a Star Portal is instant (like stepping through a curtain). However, the farther the distance being crossed, there is an exponential increase in Xylite consumption and energy use, so long jumps are seldom made due to the expense.

-'''Portal Transit Authority''': The Star Portal Network of the Republic of Allied World’s is managed exclusively by the Turuk’s Portal Transit Authority (PTA). Each gate is operated by a specially skilled Turuk, coordinating jumps with other operators by way of their connection through Nirana. Pilots/captains enter queues and are provided a scheduled time by the local PTA agent. Non-Republic species are only permitted use of the Star Portal Network by special authorization of the Senate.

 ===Navigation Checks===
-Unless the group is leaving the navigation to the professionals, a Navigation (space) check needs to be made for each transit. In the case of Hyperdrive travel, it is especially important to accurately plot the course. A minor error might only result in lost time and fuel, but a major error could result in potentially lethal encounters.

-The straight-line distance between Kinlachitobo Win (Solani Temple) to Sol (Earth) is 34.60 parsecs.
+# Slingshot around black hole, multiply miss distance by 10
+# Exposure to mysterious radiation: ???
-* Hyperspace: Acceleration at 1G reactionless drive for 3hr 50min would cross 0.05AU and give an entry velocity of 135.443 km/sec (0.05% lightspeed), which would allow the 34.60 parsecs to be transversed through hyperspace in 8 days 17hr 11min. Another 3hr 50min at 1G would be required to decelerate, so it will take about 9 days total for the tirp.

+# Veer too close to a star, ship sustains serious damage
-* Star Portal Travel would have three options based on maximum jump distance (in parsecs).
+# Hyperdrive engine burns out
-** Kinlachitobo Win -> Mogawa Win -> Niven -> Wells -> Anderson -> Sol would be 5 hops (10p max), costing $1330 with an average of 2hr 38min queue time.
