Yes and no. The lore of the relic quest conflicts with the first part I stated. The spear, the Gae Bolg, was basically the Dragoon womans fallen husbands lance. At first it wasnt the Gae Bolg but after several years of honing and fortifying it with powerful materials and metals, it became the modern Gae Bolg and she used that to kill the Dragon. Afterwards she abandoned the weapon, leading a life of cloth afterwards. (which would explain the fact the Ixal have it.)

This could also be a theory and its largely just head cannon but she could have been discovered as that she was the generations Azure Dragoon and after she went on her journey to forge the Gae Bolg and slay the wyvern who slew her love, other newer generations of Azure dragoons could have taken it up as a sort of tradition, forging a new spear for every generation of an Azure Dragoon in order to possibly replicate or just honor the Azure Dragoon who wielded the first Gae Bolg.
