In the future, NPCs will do quests for you.
In all fairness, the only way to have fully reactive NPCs would be to have someone writing for each of them full time, enact single time quests, and make the NPCs act exactly like players. There is not a single MMO that can do that right now. The effort it takes to write, edit, and test a single complex quest is extreme.
The lessons Thorian teaches you are not about Hydlaa society any more than Rolara's are. You have to take them as single quests, and assume the vindication or come-up-ins will happen. The lessons are about the limitations of the game, not the behavior of the people.
