The map hasn't many of storyline events or messages inside, only the short story to make the starting conditions clear. But it's a multiplayer map, and, as for me, it doesn't need well developed storyline ingame. Players will make the story :^).
But of course you'll have some custom heroes, items and... the battle with AI will be not so easy (guaranteed).
Here is the story:
Four underground countries deep beneath the sea finally found their Wizard Leaders.
Great magic created Isles of Fire, the way to connect the underground world with
the surface. The underground Wizards are dreaming of conquest in the light of the Sun. But a small nasty surprise awaits them... The light world already has the powerful Old Wizards, and they don't plan to share the power. Now the world will see, if the Prophecy of the Lizard was true, that *only who can defeat the guardians of the Dragon Ring can be the One and True Master of Magic*. The Time will show everything, but not to everyone...
