Dana
Dana is a magician who the faeries call upon to restore order to the world after the magical document known as "Solomon's Key" has been disturbed, releasing monsters all over the world. The faeries trust that Dana will use his magic powers wisely to enter the constellation Miya, and battle his way through the 12 chambers of the zodiac in order to replace the seal that protects the world from evil. Dana is a gifted magician, with a wand that allows him to create and destroy blocks at will. He must use this power to create platforms and opening for himself in order to get around and collect various objects, while avoiding a terrible fate by touching one of the monsters that roam the chambers. Dana also has a limited ability to throw flames with his magic wand, but he must first collect the power to do so and store it on his magic scroll. Throughout Dana's journey, he must attempt to collect various objects, many of them hidden from sight until he destroys a block, or creates a block in an empty space and subsequently destroys it. These items include Zodiac Symbols, Solomon Seals, the Page of Time, and the Page of Space. If Solomon manages to collect all of these things, than not only will he be able to restore the seal, but he will be able to rescue the faerie princess as well.

Goal
The goal of every stage is to find a way to, first, collect the key, and second, reach the open door. Of course, it's never as easy as it sounds. You must avoid all kinds of enemy obstacles, projectiles, and complex level layouts in order to provide Dana with a safe path that allows him to achieve these goals. Dana's ability to create and destroy blocks will be at the core of every strategy that you employ to help Dana achieve his goal.

In addition to the normal stages, there are hidden bonus stages as well, 7 in the arcade and 12 on the NES and SMS versions. To access the hidden stages in the console versions, you must find and collect the zodiac symbols. However, to access hidden stages in the arcade, you must use your wand on specific keys. If you use it at the right time, the key will turn from a red or green key, into a blue key. If you touch the blue key, it will open the door as usual, but when you enter it, it will take you to an alternate stage.

Jumping

 * Dana is an exceptionally good jumper. He can jump at least two blocks ahead, and a little higher than the height of one block.  In this manner, he can jump on top of a block that is one block higher than him and two blocks away.  He can also jump on top of a block that is three blocks away at the same height as his starting point if he stands on the edge of the initial block.
 * You can maneuver Dana with a good degree of freedom as he falls through the air. Direct Dana where you would like him to fall.  While he is falling you can also use the wand to slow your descent.  Continuously use the wand in mid-air, and Dana will pause mid-fall.  He will quickly resume his fall as soon as you stop using the wand, but you can use this technique to avoid landing on a monster that is passing beneath you.
 * Last but not least, Dana can break blocks that are immediately over his head by jumping into them. He must do this two times in order to break them completely; the first hit merely fractures the block.  Fractured blocks have no special properties.  Use the head break technique when you want to remove a block that is preventing your from jumping higher.

Block creation/destruction

 * Dana's biggest asset in his attempts to complete each stage is his ability to create and destroy blocks with his wand. Whenever Dana uses his wand in an empty space, a block will appear.  If Dana uses his wand on an existing block, that block will disappear.
 * Naturally, this trick only works on the stony blocks that are equivalent to the kind that the wand makes. You cannot, in anyway, modify or remove the gray cement blocks that compose sections of many stages.  They are permanent and must be worked around.
 * Dana can create blocks in places other than just in front of him. He can create/destroy blocks in mid-air by jumping.  He can create/destroy blocks at his feet by kneeling.  He can even create or destroy blocks that are two spaces over by stepping off the edge of one block, such that his wand is practically in the next space.  The only place that Dana can't create or destroy blocks is directly above or beneath him.

Fireballs

 * Dana has the ability to throw fireballs at his enemies. However, in order for him to do this, he must first collect the jars that contain the magic of fire.  Every time he collects a jar, a flame spell is added to his scroll until his scroll has no more room for additional spells.  (The scroll can be extended to contain more fire magic if the right item is collected.)
 * When Dana uses fire magic, a flame is removed from his scroll. The flame will them fly along until it hits a surface.  At that time, the flame will travel around the edge of whatever surface it touched until it runs out of power and dissipates.  Certain items can be collected that can extend the duration of Dana's fire magic so that they travel farther before running out.
 * Dana can throw two different types of fireballs. The normal fireball will continue to travel until it runs into one enemy.  As soon as the fireball and enemy collide, the fireball is no more.  A super fireball, on the other hand, will continue to travel even after it has hit an enemy until it runs out of power.  Super fireballs can be used to kill multiple enemies that are within range of one another.

Faeries
Throughout the game, there are faeries trapped in nearly every stage. You can rescue them, but only if you find and collect certain bells. Collecting a bell notifies a Faerie that you are in the room and that it's safe to come out. When a Faerie hears a bell, it will fly out through the stage door and begin hovering around. It will make an attempt to reach you if possible.

In the arcade version there is a second type of bell, made of gold, that attracts a white Faerie. These Faeries are worth more points and travel faster, but gold bells are hard to find. Every time you collect a Faerie, your fairy count increases by one. If you manage to collect 10 Faeries, Dana is granted an extra life, so it's worth collecting as many as possible.

There are two other types of Faeries that are found in the game. Children Faeries (shown on the left) are typically encased within blocks as soon as you arrive at particular stages. They are worth the least amount of points, but they still count towards your fairy total, so collect them if you can free them. The very last Faerie that you will encounter is the Faerie Princess (shown to the right). She was captured voluntarily so that she could guard the seal and ensure that someone like Dana would come along and close it properly.
