can you kill him after he has cured you of corpus or is there a later mission with him. I ask because i have killed him after i did his mission but i have it saved before i did. Olny thing is when i killed him it still that i have killed an important person in relation to the main quest. i want to kno if i have ruined the main quest by doing this or is there no later missions with him and that message is just part fo the game?

once you have cured corprus you can kill him, just ignore the "doom" message

he is involved with another quest which is the "letter quest" for the Telvanni...it is urgent and can be bypassed but that is the only other quest he is involved in

Thank you for this information i will wait until i have completed the leter quest after which i shall kill him again and his children and his poxy corpus friends.

Is this letter quest part of the quest to get the houses to accept you as the navarine?

nope just a normal quest

the telvanni is one of the great houses. you can only join one so if you aren't in telvanni you shouldn't have anything to worry about. I'm in the hiallu so i'll probably kill him so i can get the daedric pauldrons.

I already did the letter quest, but I still haven't gotten that far in the main quest with this character...I have too much fun wandering around.
