So your order would be:
1. Detron Crewman- They create Sentient
2. Lancer- Sentients attack and they use Grineer clones to make Grineer soldiers
3. Arid Eviscerator- The Grineer turn on the Orokin, led by Veytok, who takes Bilsa hostage.
4. Guardsman- The moon enters the void and the Old War nears its close.
5. Corrupted Ancient- Tenno betray the Orokin and kills them after pushing back the Sentient and they now focus on the Infested.
6. Anti MOA- The Grineer grow stronger in the absence of the Tenno?
What confuses me is the part if the Moas in the Corrupted Ancient lore and the Anti-MOA lore. These look like they might be interchangeable.
