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.
Whale's Jaw is a crumbling stone monument that was once in the form of a skeletal whale. Many years have past since the construction of Whale's Jaw and these days all that can be seen in the "jaw" jutting from the earth as if it is yearning for a final glimpse of sunlight before taking a plunge into the earth.
All around The Jaw are remains of oddly formed and weathered structures. They seem to have been smoothed and tumbled by severe rain or ocean currents. Most say it is just another Wonder of The World, a mystery we will never know the answer to, but some know differently... I know differently...
