While Wylmieni prepares some undead potions, she asks you to deliver a message she has written to Thylysium's High Council.
Take this letter to Senator Nimorean!
Creating the potions will take me some time. IN the meantime, we will have to inform the council in Thylysium about the events occurring here. I've jotted down a few points. Would you be so kind as to take this letter to Senator Nimorean in Thylysium?
You have to go to Thylysium and find the Senator Nimorean. The Council is that singular, big, round building in the middle of the city, so you shouldn't have any problem finding it quickly.
Once you arrive at the Council, you find Senator Nimorean waiting for you. You deliver the message and meet your goal.
Find the spot the undead are infiltrating the navel port from!
The situation seems very threatening. It could even be connected to the problems that we've been having here for a few days. Recently a few undead were spotted in the old naval port. It's a dangerous neighborhood that used to be a place of refuge for cutthroats and criminals, but since undead have been spotted not even the meanest thief will set foot in there. Please go to the old navel port and find out where the undead are entering that area from. When you have some information, report to General Denyew in the military camp.
You wait for his answer begging for a bit more excitement in the next mission: an Expedition to the Old Naval Port.
In MP games, using the recall command (F12) and going back through the portal in Thylysium will shorten the time you have to spend for this mission.
