Nolwenn Drochnós of the Tribe of Cavan was born in Forfar in 2002, as daughter of the large landowner and forestry magnate Raidri Drochnós of the Tribe of Cavan and his wife Ava. She is the oldest of three children, the other two (Finnegan, 2005, and Leonard, 2007) being boys. She often spent time in the visitor area of the Adhmad Wood Processing Plant, watching the large machines of her father's workplace bring in and process the lumber brought from the Great Woods.
She took the entrance exams for the Iris Boarding School Complex in 2008 and succeeded. In her first school year already, she fell in love with the Sensha-Do Team and its large machines, almost vowing to one day be a member of the team. In 2013, that wish was fulfilled, she became part of the team aboard one of the Toirneach Motor Gun Carriages, being the Assistant Gunner. In 2015, she was transferred to driving training for one of the Crogall Amphibious Armoured Vehicles, which she passed with flying colours and, in 2017, became vehicle commander of Ronm-Dó. Her first match as commander was watched by her parents, who almost burst with pride.
In 2019, she was promoted to Lieutenant of Ronm-Squadron. During the 2019 Iris Boarding School Complex Sensha-Do Convention, she had a short affair with a member of the Naval School Sensha-Do Team, although she does not want to say, who it was.
Nolwenn is set to graduate in 2021. After that, she wants to study, although she does not yet know what. She tends towards forestry, but she is not sure yet.
Nolwenn is a hard-working young woman. She loves big machines, but she has no idea about how to keep them running, mechanics and engineering being anything but her forte. She much rather leaves that to the professionals (who thank her for that). She is quite good in school, puts a lot of effort into it, and pulls her crewmembers along, with private lessons, if need be. However, she is not only all work and no play, Nolwenn is an avid player of football and Kyrenaian Footvolley, cheering for Tipa Fánaígh in the former.
Nolwenn is openly bisexual.
Her three crewmembers are, to Nolwenn, something akin to little sisters from different mothers. She looks out for them, keeps them out of trouble, is there for them, when they need her, including during boy-troubles.
