 * slain
 * Astromancer's Keystone

Description
Conjurer Thalerian must be stopped.

He immediately sought out my father's private study when he arrived and he has not yet emerged. I worry that he may have found a very dangerous item.

It is called the Astromancer's Keystone. It is used to manipulate the stronghold's defenses.

Such magic was meant to protect the Moon Guard- used for any other purpose and it becomes unspeakably destructive.

Retrieve the Keystone. Slay Conjurer Thalerian to get it, if you must.

Progress
Is it done?

Completion
They had no right to this power. Thank you.
