You're refering to the white Abishai, right? If I'm not mistaken(it was about a few weeks back when I completed the game), you have to first kill Nikademus's lover, Oria. She is the last of the 3 priestesses you'll meet.

1> You'll have to obtain a rank from the Game Room(ie. play the game). This requires you to pull some levers and defeat the monsters that appear on the square tiles.

2> Once you've done that, you'll receive the key to Oria's room. Go to her room chat with her for a bit, then kill her off. She'll say something vital(some kinda code you need to transport you to the room with the door that says "embrace the shadow" which is adjoining to the actual room where the "Voice" resides).

3> Go to the stairway with the painting of Kuldahar and say the phrase you learnt from Oria and viola, you'll be in the adjoining room. Now there will be a doorway with a shadow on it. Beyond the doorway is where the "Voice" can be found.

4> To open the door with the shadow, go back to where you found Nicky, and use the Lightning generator machine and point it North(be sure to change the direction of the mirror first). This will open the door if i'm not mistaken.

5> Be sure to talk to Nicky b4 you enter because he'll help you out with some spells/experience etc.

Well, good luck, mate [img]smile.gif[/img] hope this helps.
