Lutera is a world very much like the Middle Ages, except for one thing, in this world the value of a human being is created by his level and his mode.
The level is how far the person has taken their power.
The mode is the way in it increases its level, there are several modes, in the most known way is that by the physical one.
The most powerful sound modes: by eating and getting burned
The weakest modes are: by breathing and electricity.
The modes are randomly distributed at birth, you can be the king's son and have the weakest mode or have the most powerful mode by being a commoner.
In this world 86% of people have as a mode that of playing sports, in itself this does not change too much from the Middle Ages, because those who have the mode by the physical efforts are normal humans, but the remaining 14% are not similar, they are modes to increase its level faster or increase its level more slowly.
Mode that increases the level quickly: per eaten
Mode that increases the level slowly: by electricity
Each mode has its own effect, the one per eaten, allows the eater to use the affinities of what he has eaten, for example having a prodigious force when you have eaten beef.
That by electricity allows the person struck by the lightning to produce discharges.
That by fire, allows the burnt person to produce combustion.
And finally the one by breathing, this mode is considered to be a very rare and incurable disease, this mode allows the person to use nothing, moreover the person who has this mode cannot increase of level.
In addition to know, in Lutera children are born at level 0 and must increase their level except that by breathing which originated at level UNKNOWN and cannot change it.
