The Pyromancer's Grimoire (Alliance)

for those who are having trouble :

from the entrance head straight acros the dentention block and upon entering the other side (the halls of law) turn right for an entrance to an arena. complete this event for a special path
as soon as you reach the top of the ramp out of the Ring of Law immediately turn right twice (turn around) for another ramp up to the ring of law spectators head to the other end for another doorway and turn right and the end of this hallway is Loregrain along with the 6-8 twilight emissarys
hope i helped!

And this is so easy to get to. Go into the main entrance of the instance. Take the mole to the domicile, you are were u need to be. Easie as pie!

To get to the entrance of black rock depths:

Inside blackrock mountain (between searig gorge and buring steppes) you fly down towards the magma. One of the chains coming from the floating rock in the center leads to a little platform with a blood/high elf character present (those who run MC will recognize him as the npc that takes you straight to molten core). before the little room with the elf, turn right into a cave. At the end of the cave is the entrance to Black rock depths.

Once inside, take the mole machine to the domicile. there are twilight emissarys all around, and the bridge with all the fire elementals leads in a striaght corridor to the named npc you have to kill.
