Eolinius was born in the Prime Roots and didn't see the light of day very often during his early childhood.

His parents travelled the Prime Roots to teach the little homins of the lost tribes the rudiments of education. He was thus moved from tribe to tribe developing a curiosity about everything around him, which was not lacking in this underground world full of strangeness. He still has a moving memory, fascinated by all the colors he liked to run after as a child^[1].

He always wondered about the exact activity of his parents, who besides teaching, also practiced strange scientific activities by excavating the ruins of the Prime Roots and sometimes meeting people there in a discreet way.. His carefree childhood ended abruptly during an expedition in which his parents died after the appearance of "shadows" as he called them as a child. Eolinius, who should have ended up like them, was mysteriously saved by an inexplicable phenomenon (an unknown light enveloping and protecting him). Left alone, a passing Ranger patrol picked him up and took him to Silan.
