I have problems to find the chalice too.

I sent the damon to the Compass Room and followed but there are no bounty hunters

What can I do now to solve the quest?

BLW Review (caution contains spoilers)

I have just finished Mod BLW for the first time and
I've got to say I am thrilled. I'll definitely include
it during my next couple of runs of Baldur's Gate.

Characters: Kova and Kiyone are very interesting
characters. They are very different from each other
and that's precisely what's so exciting about them. I
also likes the fact that they stay in character
throughout the course of the game and don't change or
lose coherence. That is usually one of the challenges
with mods, but it has worked out perfectly here.

Quest: The quest is extensive and last throughout the
whole game. It's fascinating to complete the puzzle
piece by piece, to find out what exactly happened and
why. The quest also includes some challenging fights
in which you absolutely have to make the right
decisions or face serious consequences (e.g. when you
accompany the eye witness).

Romance: The romance is slowly building up pace
throughout the game. It's very enjoyable to see them
fighting like cats and dogs before they finally grow
close. I especially liked the wedding part, which even
made my eyes mist over a little. Their conversation in
front of the temple was my absolute favorite. However,
I didn't listen in on their wedding night.

Now I've included them in TOB and was very happy to
find that they still had something to say in Watcher's
Keep.

I think this is a particularly successful mod.
Everyone should give it a try at least once.
