On the horizon, you spy a island devoid of vegitation. In its centre sits a single, exceedingly tall tower.
Only needed if the players will notice something when they land on an island that they wouldn't see from a distance. This is the description they receive when they land on the island.
Include at least two images here, one for GM use with everything marked, the other for player use with the location names omitted. The player map can be purchased from a demon of Pascalentue somewhere within the region, usually at sea.
The spire has an enormous door at its foot. There appears to be no other way to enter. The door will be locked and impossible to penetrate (due to magic) unless the players have collected three crystals from enemies around the world map (Silent, Ironclad and Defect).
At the base of the spire, the players will be greeted by an image of a man who tells them they have proven themselves worthy by being able to enter. He explains that each floor will give them a new challenge to overcome. They can go up, but not down. If they make it to the top, they will be handsomely rewarded. Before rising to a new floor, they will sometimes be given a choice of what sort of challenge they would like in the next floor.
On the first floor, the players get a simple combat encounter against a single enemy
Before ascending to the second floor, the players are given options. One symbol shows the head of a monster. The other shows a ?
If the players choose the head of a monster, they will go into a combat encounter against three small enemies
If the players choose the ?, they will
This would be things like journal entries. If there are dungeons on the islands, the maps should be here (or at least linked to from here if it's a TTS map).
