Weakening of the Veil - Elder Wizard

It’s been too long since I started to get things organized. I would like to invite people to consider the character of an elder wizard type of person. Basically the plot will need someone who can read the ancient magic which composes the barrier to the Dark Aether. Rather than a standard wise-man style I’d like to investigate different archetypes for such a person. They will be integral to the plot of course but I want the interaction to have more depth than just a wise-man style giving sage advice.

Any thoughts?
