Sister Llorissa can be found in the Monastery of Saint Veloth.

Doesn't ring a bell. One of the Temple priests might know where she is.

The Temple is strong in Almas Thirr. You should seek for her there.

Speaking.

It seems that killing her made the ghosts disappear. Fancy that. Here's your reward, mortal. The Antumbral Shield of Moonshadow. Knock yourself out.

That's got it done.

Then stay out of my way. She has to die!

You don't have any say in this matter, you fool! She has to die!

Together then. Mortals first.

You're supposed to be the Nerevarine, aren't you? So, be a good little pawn and kill Llorissa. I command it in the name of Lady Azura.

Listen, mortal... Are you going to believe her or are you going to believe me? Now be a good little pawn and kill her.

Here's your reward for dealing with the ghosts. The Antumbral Shield of Moonshadow -- a gift from a goddess. Knock yourself out. But... Llorissa Faali is still alive and breathing. This I can not have. She must answer for her transgression against Lady Azura.

[In a blink of an eye, Aizuhr-Suur disappears.]

You let her go? You absolute fool! Useless... useless beyond words... I'll do her in myself!

So Llorissa Faali is the one behind the Ordinator attack? She's hiding under the Temple's skirt in Almas Thirr? You should go there and find her. And, well, you know... kill her. That's what I'd do.
