"Prentan" is "spring" and "etènèl", named this only after Adomi died and created an eternal spring.
The area more dense with mountains, and used to suffer from a curse of very extreme weather conditions. During Adomi's time, he would consistently manage the curse to lesser affects. In fear that the extreme conditions would return in his absence, Adomi chose the taboo/reverse-tarot option of creating a eternal spring in the area by destroying his heart right before his death.
Because of it's high vantage point, it is easy to view Seul ke from the peaks.
Adomi was born here.
