Crus listens to you story with interest and he is quite displeased to hear the news about Kyle.
Seeing you casting your spells of detection he frowns again displeased.
"It's quite rude to come into a man home and to use magic to try and sense his soul like your doing. You wont sense anything from me but I assure you I have no bearing towards evil if that is what you're worried about."
He lets you finish and continues.
"I am familiar with Graylock, he is a formidable warrior. Beyond your skill at this time I believe. Assassination is not his usual method however and deathblade is a rare and expensive poison. Someone must have paid him a hefty sum to do it."
He takes the note and frown as he reads it.
"You found this on a hobgoblin in the fort?...This complicates things. I have been aware of the white fist for some time but I did not think they were this bold...This letter is a reply to the leader of the whitefist orcs were the hobgoblins are agreeing to his terms and will join in his attack on Magnimar. Since you defeated the hobgoblins they will not be able to do so however but it's likely that this attack is still going to happen...Could Kyle's assassination be related to this?"
Crus is silent for a moment.
"It seems I will be putting my studies aside for a time and getting involved once more. I thank you for bringing this matter to my attention."
He considers you for a moment thinking.
"I have a task for you if you're willing. You aware that tunnels going trough the underdark pass all around this area well some of those tunnels stretch all the way to Galduria. In those tunnels is an ancient temple to Charon, I have believe Kyle's uncle has been making regular trips to this temple for some time. You could travel there by underdark but it would be safer to travel overland and find an entrance to the underdark once you get there. I think investigating this temple will go a long way towards convincing Wycheck to have his nephew revived."
