Cracking the Code

Objectives
Raelorasz at the Transitus Shield wants you to get the Azure Codex from Inquisitor Caleras and collect 3 Shimmering Runes from his Coldarra Spellbinders.
 * Shimmering Rune: (3)
 * Azure Codex

Description
I sense a distinct peculiarity in the drakes here but the meaning of the runes that cover their bodies still eludes me.

Without a codex, it will take more time than we can afford for me to interpret them.

Not far from here is a Kirin Tor traitor, Caleras, who is likely to have a copy of the tome I require. His underlings hold the runes I will need for my translation.

Hurry, mortal. Malygos gains strength with every passing moment.

Progress
Hurry, mortal.

Malygos gains strength with every passing moment.

Completion
You have done well,.

Let us hope for a clue that we can use against Malygos.
