"We were betrayed" was Hank's opening remark.
It wasn't complicated. Last evening, Serena brought them to Blackhills Town to collect a lot of supplies. However, their carriage was ambushed just as they were halfway through their journey. Hank vividly remembered that it was Rode who had attacked them.
It was simply too much of a coincidence—just as if it had been planned. It happened when Serena brought only a few of them to Blackhills Town for the handover.
Serena took only six people at that time, including Hank, all of whom were low-level adventurers below level-ten. Moreover, Serena did not bring the Gryphon along. The Silver Hand had suffered a big loss in this sneak attack. The battle was almost one-sided; the men that Rode had brought along were all around level-ten, and it was a surprise attack to boot. They had killed two of Silver Hand's men upon appearing.
