To change from Aldor to Scryers in WoW TBC, go to Lower City, Shattrath , and speak with Arcanist Adyria at about 54, 22. She gives the repeatable quest Voren’thal’s Visions , which asks for Dampscale Basilisk Eyes ; turn those in until your Scryer reputation reaches Neutral , then you can continue normal Scryer rep gains.

Steps

  1. Travel to Shattrath City → Lower City.
  2. Find Arcanist Adyria.
  3. Accept Voren’thal’s Visions.
  4. Farm Dampscale Basilisk Eyes from basilisks in Terokkar Forest.
  5. Repeat the turn-in until you hit Neutral with Scryers.

Important detail

  • This switch does not instantly flip you over; it’s a reputation grind back to Neutral first.
  • Once neutral, standard Scryer reputation turn-ins become available again.

Quick note

If you meant the opposite switch, Scryers to Aldor , that uses Sha’nir and Dreadfang Venom Sacs instead.

TL;DR: Go to Arcanist Adyria in Lower City, turn in Dampscale Basilisk Eyes repeatedly, and grind Scryers back to Neutral.
