No offense DW but from an RP/story/character development perspective it is almost good that your fight is going this way. I could RP with you in the nether void with your family. In the story you would miss your chance to go with Tira (something I am planning already) and the lower lvl group would go. And as for Jareth he might become alittle more cautions in fights knowing that he can't get the vengence he seeks by blindly going into a fight or all out. He just may learn some patience. And his hatred for the Treylor would increase ten fold.
No worries about dying remember Brend is a 9th lvl cleric

(oh that reminds me raise dead is strongly houseruled in every game I have ever ran, no way it takes only one minute to cast, and doesn't cost a lvl but worse a point of CON)
