It was an effective trade route as all runs except the one through Silesia were covered by termini of the Manticore Wormhole Junction. However, the Silesian run was troubled by piracy, thus merchant ships were often escorted by warships of the Royal Manticoran Navy or the Imperial Andermani Navy. One of the most dangerous spots for the convoys was the Selker Rift, a gap between two hyperspace grav waves on the way from Andermani to Silesian space that had to be crossed at sublight speed to dodge another, exteremly dangerous "rogue wave".
