The Sigurdson family comes from Lannock in the southern reaches of Olaran - a minor noble house with a dragon crest, they were once vassal to Duke Killian. Tagelia (or “Tag” as many call her")’s father, the Baron Sigurdson, had seen many years of bloodshed at the border and swore fierce loyalty to his lord, the Duke of Lannock (who fought and knew the threats in the south as other nobles did not). In her youth she trained with the Rangers of Olaran at the borders and witnessed the murder of King Osric at the famed Autumn Feast. In the early years of the Hearth-Guard, when the elite soldiers of Olaran served directly under the Duke, her father swore her sword to serve their liege lord to uphold honor of her father and house.

Tag served loyally in the Hearth-Guard for many years as a passionate supporter of both Duke Killian and her own family. She served in the expeditions in Ithacus for the Sword of Hope and was one of the few shieldwall survivors at the Battle of the Fort, betrayed by Rangers she once trained and fought with. Shortly before the First Battle of the Thornwood, when Duke Killian willingly abandoned his adherence of the Old Ways and took up the vow of the Holy Order of Luminos in order to save himself, Tag (along with many Hearth-Guard) felt betrayed by the cowardice of her leader. This choice of Killian’s, however, also stripped Tag of her vassalship to her former lord that had been made in her father’s name.

Consumed by her rage and loss, she forsook any vow to ruler and house, and swore to only hold allegiance to her shieldkin - those she has fought and bled with.As the Hearthguard fought for land in the following years,she devoted herself as Valkyrie, leader of the furies,and as a commander of the mighty shieldwall.

But the founding of the Hearthlands was a fresh beginning, built on a new oath to serve her queen and her people. Newly crowned, Queen Tove named three jarls to lead the Hearthlands in her name. Tag was given the southlands, including Lannock, her family's homeland who they once served vassal for. Jarl Tagelia now divides her time between building trade and commerce in Lannock and overseeing troops at the fortress of Bash Tiar.
