Squish, Squish. Squish.
Bogmoors has been here for 721 years. It started with an ale stop for the Imperial invaders. From there it has been a similar stop for every wave of invaders since then, as well as every local for a good walk’s distance.
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.
