Way to unlock: Find the tome at the pillar.
Quest giver: - (M9,7)
After you find the tome next to the second pillar with the beacon, you receive the quest to kill the apostate Widris, whom you find hiding behind the first Rift (M9,7a). The mage uses minor specters to his aid, but the fight is not too much of a problem. After you defeat him, in one of the crates, you find a scheme, and the barrier reinforcing device (interaction possible after the "Scouting the Cover" quest).
Rewards for completing the quest:
- Experience (lots)
- 200 Influence points
- 2 Power points
