The Empty Shrine-Perch is a high spire or bell-tower the Order uses as a place to descend from, never to hold — its bell long silent, its firing position always, pointedly, empty.
A friendly jump-capable fighter wholly on the Empty Perch gains +1 to Hit with pistols and jump-range weapons against targets below it. At the end of any round in which a friendly occupied the Perch, that fighter may make a free jump move of up to 6" off it. The Silent Order never holds the high ground — it only uses it, and is gone before the ground can be taken from it.
