Stronghold random events (Pillars of Eternity)

After securing the Caed Nua stronghold, there is a chance for unexpected events to take place at the stronghold every turn. The events are partially dictated by the Prestige and Security of the house, its purchased upgrades, and hirelings in the player's employ. When a random event occurs, you will be told regardless of whether or not you are physically there. Sometimes, you will need to deal with the event immediately, but usually you are given some time to decide what to do.

Visitors
The most common event at your stronghold is having a visitor arrive. There are all kinds of visitors, but they all share one thing. They can adjust your prestige and/or security just by being at your stronghold.
 * Some visitors give good bonuses and some of these visitors can even be employed as hirelings and will stay on as long as you pay them.
 * Others are not so great, and you can pay them to leave, or get one of your unassigned companions to act as an escort to their next location (making the companion unavailable for a time).
 * Some visitors will offer rare items for sale, and some might even offer a very rare item in exchange for one of the prisoners in your dungeon. Items acquired this way can be found in the treasure chest in the Main Keep.
 * Visitors normally wait 9 days for your decision and any decision (not ignoring) yields 200 xp.

If Visitors die during their stay, the stronghold suffers a Prestige penalty for a while.

Adventures
After the Great Hall is restored, an adventure becomes available though the stronghold management interface on every turn with a number divisible by 8. Unlike quests, you cannot resolve these yourself - you must assign one of your idle companions to complete the adventure, making them unavailable for the specified number of turns.

If you don't assign anyone to it, the adventure disappears after a limited time. Once you've assigned a companion to it, recalling them prematurely cancels the adventure and forfeits any rewards that would have been earned. If the adventure is completed, money and item rewards from the adventure are placed in the treasury chest of the Great Hall, and the companion who was assigned gets additional XP (not shared with the party).

The adventures you can get are:

Which adventures you get is determined as follows:

 Each turn, the game rolls for an event. If that event is Adventure (and you don't already have an active adventure), then the game rolls two random numbers between between 1 and 50, adds them to the stronghold's current Prestige number, and uses this sum to determine the adventure category: From the selected category, a random adventure is picked that hasn't been picked already. (You need to exhaust all unique adventures in one category to get a generic adventure.) 

Attacks
Attacks are the most potentially dangerous of all stronghold events. Attack losses and frequency decrease with higher security. The threat of attacks is the most important reason to keep your security level as high as you can afford.

You will be warned ahead of time of any such attack, and are presented with three choices:
 * 1) Manual Resolve: Your party and hirelings battle the invaders. If you are not at your stronghold, you  must return before you can select this option. This option usually results in the best outcome, although some of your hirelings may be killed.
 * 2) Auto-Resolve: Your hirelings battle the invaders without you. This usually results in the destruction of parts of your stronghold, which you will then have to rebuild, expending time and money. In the meantime, you lose their benefits.
 * 3) You can ignore the warning. If you continue to ignore it until the time runs out, an auto-resolve will happen.
