Durgan doesn't trust them entirely, so he walks behind them as though escorting them out.
Sessativa cries for real, but it is only a short burst of tears. She gets up and watches the men go.
They reveal to Zork, "There was a spy with those guards, we have to get out of here and leave no trace. I can make two people invisible and teleport myself out. We have to carry our gear on our backs and leave the horses and belongings behind - maybe sell them, but that will slow us down. Most of our non-magical valuables should go in our hidey-hole, some should be left out as a diversion. Then we make our way to Lady Estari without arousing suspicion. Agreed?"
She turns to the messenger from Estari, "When I give the go-ahead you will take our best horse and ride towards your lady. We will try to meet up with you on the first night, but just in case, I and I alone also know the location. Can you do that without anyone following you?"
The messenger smiles and says, "You worry about yourself. Meet me on the road a mile south of way station that is currently being placed where the hill fort used to be. I will meet you there." With that she slips out the back of the house and soon is gone. She does not take a horse.
"Well, Zork," Sessativa begins asking, "How will we do this? Rest until tomorrow so I can be fully prepared? It's just that I only have 1 invisibility to cast today and I can only teleport myself.
"Or do you want it to appear that you're leaving for your fort by yourself, but you're actually with Durgan and I'll teleport straight there? I just want to avoid raising their suspicion."
"The teleport idea is good, let's do it." Zork calls his dog, mounts his horse and sets his sights back for the fort.
I will need a list of what you leave behind and what you take with you. You are saying that Durgan will be invisible riding behind Zork as he makes his way back to the hill fort? Where will Sessativa be teleporting to? This will be a specific area.
