“ Some parallel worlds have different time-flows, like the fabled dwelling-places of the elves: those who visit them under the hill for a night return to find that years have passed in this world. Perhaps it is the gate leading between the worlds which causes the alteration. If a gate were 'misaligned', the shift from '| |' to '| \' or '| /' as it were would lead to that difference, much as a light-beam split and bent by a prism ends up taking a longer path. There might even be a mathematical function linking degree of misalignment to alteration of time-rate.”
“ Go Beyonde
Wiz 1
For one full round, a gate to another dimension is opened. That Dimension is called Beyonde. It is a place of eldritch horrors but if you are careful, movement there for every 10 feet there you cover 1 mile here. It is very dangerous and creatures will attack). near instantaneously upon your arrival. in practice, you can roughly cover about 300 miles(after this point you will be subjected to overwhelming attack.Brave(Foolish?) peeps attempt to send armies through, that is very iffy. you can only get to approx. D^ miles of where you want to come out(requiring another casting of the spell.
Basically you have teleportation available to L 1 Wizard's , this would shake kingdoms to the core, if an enemy army could appear at any moment,D6 miles from a target. Warfare becomes very fluid and much smaller forces are scattered about the countryside.”
“ Medieval Britons didn't write contracts. Instead, men making agreements would clap their knives onto an altar and recite the agreement three times to seal a deal. Even after the Normans introduced written contracts, British nobles would wrap the parchment around a knife to authenticate it.”
