He planned to develop a proof of commonality between the two philosophies using the unique properties of mercury.  He believed that this was possible due to a very old tome that he discovered.  This book contained the sum of knowledge of an ancient alchemist who was sure that mercury contained the answer of most questions of the then known universe.

Combining both forms of physics and alchemy proved to be tricky, for none of his experiments worked.  Most failures had no effect, some failures were flashy, but not dangerous.  One destroyed his lab, and apparently him as well.

Through some unknown agency, he found himself on a world that was constantly shrouded in mist that had several moons.  The body that he occupied seemed to be a shimmering blob of metal.  It took him several years before he learned how to control his new body, or even move.  His initial movements were like that of an amoebae.  Eventually, he learned to master his new form, changing his appearance at will, even learning how to change the coloration of his skin.

That is when he learned where he was, Munnopor.  An extra-dimensional, intelligent planetary system that sometimes allowed mortals to draw from its power.  The original author of the alchemical tome was one such mortal, and a many generations past ancestor.

The tome was a sort of appeasement to Munnopor do to an estrangement caused by his ancestors actions.  Munnopor did not accept the offering, due to the fact that it already knew all of that information.  Mercury had added to the knowledge that was in the book, in ways unforeseen, and unknown.  Munnopor requested an explanation of Michael's work and discoveries.

When Michael was returned to the Earth dimension, and Earth itself, he knew of, and could develop his magical abilities, which had been boosted by the entity.  However, it was 1989.  When Michael tried to bring his discoveries to light, he was scoffed at, some actually laughed.
