Hunter-Killers, as a whole, were not usually ones to ask for help. People came to THEM for help, they did not go looking for it themselves.
There were situations that even a Hunter-Killer did not want to face alone. For that, there were fireteams. Most HKs operated in groups of 4 for that very reason.
And for the ones that went beyond that...sometimes, you had to grit your teeth, swallow your pride, and go ask for the help of someone bigger than yourself.
In this particular case, as Ash noted dryly to himself, bigger both politically AND physically.
And so, here he stood, upon the landing pad of the private mansion of the Lord Protector of Vale as his ride took off behind him to head back to the Spirit of Ice, wondering if he should just go up and knock or if he should call first.
Well...he was probably recognizable to the staff, he had been here at least once...
And so, he did, striding forward and wrapping upon the door.
