However, the Redguard Warden does get a name and a backstory in Naryu's journal. Maybe we'll get the same for the high elf in Raz's journal.
Possibly, though we already know her as the Dominion Hero from the original launch Cinematics, coming back home after her ordeal during the Siege of the Imperial City. And Basically out of the three she's the only one left. The Covenant Hero died and the Pact Hero is assumingly still a prisoner in Coldharbour. If we're lucky she may even be an NPC in Summerset's story Quest.
