Generation 20 will require you to talk to Altam about different subjects as you unlock them by reading through Altam's Journal. Doing this will unlock different conversation choices with the NPCs in Generation 20.
For example, in the quest, “Eternal Memories,” you will have to talk to Altam about the Alban Knights Training Ground to unlock a third option for Caswyn. You will need this third option to progress with that quest. Be sure to always read through Altam's Journal and talk to Altam!
