Arduino was born as the new scion of the line of Poggle, a great family of Druids. Members of this family took on the responsibility of becoming a warden of nature, a Druid, and were uniquely suited for this task; due to an age-old dalliance with the fey, Poggle blood ran thick with the magic of the forest. Arduino grew into one of the finest heroes of the forest, defending it even against the onslaught of the Worldwound and its demons, widely known as a great and wise man.
Sadly, his son would not inherit those same qualities.
Arduino the Lesser grew into a callow youth, rich with laziness and fickle will and poor in quickness of mind and connection with nature. Knowing his son was not ready, Arduino the Greater delayed his time of Druidic trial. After years of little improvement, the father finally gave up and sent his son out into the world, telling him to return with a connection to nature or not at all.
It has been three years since he left. Meeting other humans and being thrust into the fascinating new environments of Korvosa and other human settlements has done wonders for Arduino, though he still emits an outward image of laziness; whether that is his true personality or whether that is becoming simply a mask he wears requires further observation.
