During the Second Exodus, most of the Valkar fled the East on a Landberg that set down on the western slopes of the Coastal Mountains. From there, they disbursed in bands to fight the Empire, often alongside West-Realm or Swordland forces. A member of the Valkar is called a Valkara.
Rubetha provided all of the Valkar a Maiden’s Mirror, and many successfully performed the Unicorn Ritual with the mirror to Bond with a Unicorn.
The Fate of the Doom of the Valkar specified that when any male defeated a Valkara in her chosen area of expertise, the two were inherently betrothed as their Stargons became mutually transparent. After a brief day and night of bliss, the erstwhile Valkara suffered an overpowering (and eventually debilitating) Migration Urge, forcing her to disappear to a location still unknown to the outside world at the start of our story.
