I am trapped in the sphere and my mage is dead, I have killed Lavok and have really hard trouble getting further =..( What to do?

Did Lavok tell you to go get something to make the Sphere work?

Welcome to Ironworks (I'm rather new here 2 so :D )...

Didn't Lavok mentions something about a ''heart'' or something (don't wanna spoil if you dont ask for it)

uhuh uhuh he should say something about somekinda heart hint hint
if you need more then that ask again .

look deep in thyn heart n thy shall florish
ok ok that was totally uncalled for ...... ignore that .

See ya

i was stuck in that part too for a while, until i noticed something different in one the rooms(hint hint).

Another hint is contained in Chapter 13 of my site, if you want one.
