Where is she hiding at? I looked in Rogues Gallery in FP, nope. I looked in reg gallery, nope. I looked in Neriak for this merc, nope. I found the NPC, but no merc. I redeemed this token, which means according to your rules I can redeem her and the narrative says to go to Rogue Gallery in FP or Qeynos. Where can I hire her at? Fair question - right?
She's available in the Rogue's Gallery, second level down, in the "Notable NPCs - Archon" area. She's the second one down on the right, making her a rare. My monk (lvl 90) has her and she fights well for a healer.
