The Rookery is the Ravens' headquarters. Here you will find information about the players.

If a player retires a character, that character becomes a trainer (see below) and contributes to a Bonus XP pool. All future characters created by that player will start with an additional amount of XP equal to their Bonus XP. Bonus XP is a function of the total number of missions run by all retired characters combined, as such:

So if you've got three retired characters with a total number of missions between them equal to 23, all future characters you create start with +6 XP right away. If you retire another one after 5 missions to bring your total retiree missions to 28, future characters start with +7 XP instead.

This formula is also used on an individual rather than aggregate level to to determine trainer offerings and tribute bonuses for retired and dead characters respectively.

Few adventurers ever accomplish the feat of completely mastering an ability tree. Here are those who did.

If you master an ability tree, you get a -1 Supply discount on purchasing abilities from that tree for all of your other characters. This discount stacks with all other discounts, but not with itself (you cannot get it more than once for a given tree). Total discounts cannot lower Supply costs below 0.

Trainers offer opportunities to anyone on demand in their specialized areas, but they can only be taken advantage of once apiece. Trainer opportunities can be used in place of a keystone to learn a new ability. For example, the trainer Ambrose Glenham offers an opportunity in both the Grit and Shield ability trees. If your adventurer learns a Grit ability from Ambrose, they cannot ever do so again but they still have the capacity to learn one Shield ability later at a time of their choosing. If another trainer also offers a Grit opportunity (such as Bridget), you can also take advantage of theirs (but just once).

Players can choose to retire any of their characters that have survived at least one mission and make them into trainers at the Rookery. A retired trainer offers a number of opportunities equal to the bonus XP they would be worth on their own without considering any other retired characters of the same player.

By paying your tributes to the dead, you can strengthen your own resolve going forward. You can attempt to tribute once per session by rolling a die. If you get a 9+, you successfully meditate on the lessons offered by the deaths of those that came before you and immediately gain an amount of XP equal to the amount of bonus XP that character would have been worth on their own without considering any other retired characters of the same player. A single character cannot tribute any given fallen Raven for the XP bonus more than once.
