A few fails here and there, but what seems to work best for me:

1. Caphras' Seal
2. Alchemy and Gorgath
3. Secret Guards II
4. Origin of Ancient Light
5. Origin of the Crimson Flame
6. Troop of Darkness I

When it all goes through:

1) Troop of Darkness II
2) Secret Guards II
3) Origin of the Crimson Flame
4) Caphra's Secret Lab
5) Secret Guards I
5) Origin of Ancient Light

In order to preserve the high favor gain by the Secret Guards II and Origin of Ancient Light, high interest topics should be placed after them to maximize the favor gain.

#1 Origin of Earth
#2 Secret Guards I
#3 Secret Guards II
#4 Origin of Ancient Light
#5 The Watchtower Conspiracy
#6 Resurrection of Belmorn

1. Печать Кафраса
2. Алхимик Горгас
3. Секретная охранная группа II
4. Основание древнего света
5. Исток огня
6. Армия Тьмы II
