Sylvestra had already arrived at the Paladin HQ hours before by early morning. She and her company had been tracking the Azure Covenant's moves for months and she too was quite sure they were holding up in the Black Forest, like rumors speculated. Judging by where and when they hit, it was all random when looking on a map, but Sylvestra thought it was only an illusion of random if they all came from the same place. She was already deep in discussion with other commanders about it when more Paladins began arriving to HQ. She didn't pause her discussions with the other commanders whenever she saw a new arrival, but she did look up to glance at them. It was just something she did whenever a person entered the room, so she could keep track of the number of people and their equippment currently.
The other commanders didn't know the reason for the letter either, so Sylvestra knew this was straight from the top, maybe even Grinnoc himself. Sylvestra guessed they would all be called for a meeting soon to explain the situation so she might aswell inspect her troops and hand out orders while she's gone, if there were any orders to give that is.
The company was resting in the barracks but Sylvestra called for her lieutenants and told them of the situation. The men would be on leave until further notice. 

Walking back into HQ, Sylvestra nodded at and saluted several Paladins who payed her rank proper respect. Now all she could do was wait until the higher-ups called a meeting. She began wondering how many had received this letter. Ten men? A hundred? A thousand? Judging from the amount of Paladins reporting to HQ, Sylvestra was sure it was at least well over ten. This wouldn't be a small operation if the suspicions of the letter having to do with the Azure Covenant and the Black Forest were true.
