Quest Issue: Life leech quest broken/unimplemented

[Pheer]

The life leech quest seems to be broken or unimplemented.

Kazzel D`Leryt is spawned and wanders, but does not respond to hails from anyone, even level 50s.

Xenyari Lisariel is not spawned, should be always up and wandering around the northwestern part of rathe mountains near the unkempt druids.

Darfumpel Zirubbel is spawned and responds to hails, but I havent had the balls to try to hand kazzel 2kpp to see if i can get the hyacinth to turn in to darfumpel.
