The
first ever earthquake rocks Eternia as Skeletor and King Hiss cause
Grayskull Tower, Central Tower, and Viper Tower to rise from beneath
the ground. The three hold the secrets to ultimate power, Grayskull
Tower representing all good, Viper all bad, and Central holding
both. While both plan how they will deceive each other, the heroes
help those wounded in the quake. The Sorceress then notifies He-Man
of the rise of the towers and explains the Ancients sunk them to
keep them from being captured by King Hiss during his siege. It
ends when Skeletor then He-Man gain ultimate power, but He-Man prevails,
and realizes the significance of these towers: they are now the
ultimate battleground.
