How would Mathilde react if Aksel came to her tomorrow and asked for complete written copies of all of the lore and secrets of the Grey Order?
/jk: How good would be be at making sure the rest of the Order would not find out and would he be willing to trade
Seriously though do not ask for the secrets of the literal mystery cult guys, not only would they not be willing to hand it to us, they are most likely not even able to because they are not written down.
