The Hunt wrote:Playable on Alatar during the organization phase. Name a specific hazard creature card your opponent revealed to you through a mechanism of the game and discarded. Unless eliminated or prevented from being in play, your opponent then finds this particular card (reshuffling his play deck if it was searched). This creature immediately attacks Alatar as though he were a one-character company. Alatar cannot use or benefit from spells against the attack. If untapped, tap Alatar afterwards.

Dark Numbers wrote:Stolen Knowledge. Playable on an untapped scout immediately after facing an Orc, Troll, or Man attack. Tap scout. Can be stored at a Haven [ ]. If not stored, discard to give +3 to an influence attempt against a faction by a character in the same company.

Knights of the Prince wrote:Unique. Dúnedain. Four strikes. Detainment against hero companies. Playable at Anfalas, Belfalas, Lamedon, Lebennin, or Anórien; or at sites in these regions. Unless the attack is canceled, all untapped characters in defending company are tapped following this attack.

Creature that attacks Alatar in result of The Hunt attacks him as though he were a one-character company.

Whole Alatar's company will have in its history a facing of Knights of the Prince, or a facing an Orc, Troll, or Man attack. Because Alatar who faced such attack is a member of the company.
But whether other untapped characters in the company will be tapped after facing Knights of the Prince by Alatar, or whether Dark Numbers may be played on an untapped scout in the company?

Dark Numbers is not a good example as it can be used after Man attacks not Dunedain attacks - No News of Our Riding might be a better example

Knights of the Prince is example of card that makes after-attack actions Unless the attack is canceled, all untapped characters in defending company are tapped following this attack.. For Orc, Troll, or Man attack. I did not provide any example.

I wonder whether [facing of attack] as though he were a one-character company is obstacle that prevents an extending Knights of the Prince's after-attack actions on other characters in Alatar's company and whether other character in Alatar's company is considering immediately facing an Orc, Troll, or Man attack that Alatar faced in result of The Hunt.

Similar question as for Dark Numbers applies to the No News of Our Riding, of course.
