In some future update, it is planned to add quests where you go to other islands to meet people who require your skills, although for this I must first solve some technical limitations regarding water and long distances in the game.
Regarding the towers... The planet of the game is one with a very high percentage of water, the creatures live scattered on different islands.
The towers generate energy with water, it represents that they create gravitational fields with which the water moves upwards and goes into an internal cylinder where the speed of the falling water is used to generate energy. At the same time they power themselves to operate as a telecommunications tower.
