Portale

"There is only one real way to scratch your back", the sage on the top of the highest mountain in the karvel told me "and it is the only way to make appropriate use of portals.". With that he started murmuring and his eyes started to get paler with every word of the incantation he spoke. When he had finally finished after half an hour a small portal, maybe large enough to fit a finger through appeared in front of him. He put out his arm and entered the portal with his index finger, when a sudden sensation of something in my mouth interrupted my meditative trance. I was confused at first, but then it hit me, ew. "Embrace the ridiculous.", the old man smiled.

Energieerzeugung

The mages who create it have to supply magical energy in a suitable way to keep the portal open.

Zusatz- & Hilfssysteme

Sometimes a portal can lead to a hub of other portals all leading to different worlds, thus making it far more versatil, but the hubs or portals in them can be unstable.

Motto

Von A nach B, ohne Verzögerung.

Preis

It is very hard to open a portal or even learn about the steps required to do it, so the price is horrendous and would even empty the Emperors pockets.

Seltenheit

Being so incredibly hard to achieve it is the rarest of all transportation methods.

Länge

None. A portal is strictly two-dimensional.

Höhe

It depends on the way it was created.

Gewicht

It is very light, and is not affected by gravity at all, so the weight has never been measured. As it has energy, the undiscovered laws of relativity state thet it has some mass.

Geschwindigkeit

Instantaneous, you get from one place to another without being anywhere inbetween these places.

Besatzung/Crew

To open a portal a team of highly skilled mages, who are trained in combining their powers.

Fracht- & Personenkapazität

As long as the passage exists, things can travel through it, so it wouldn't be impossible to transport entire armies.
