|Services||Detect Hidden Trainer|
Ney Csalan is a Master level Detect Hidden Trainer in Mel Senshir. She is friendly with the Warsworn Faction. If you accept the Khamazandus' Gift quest and take the Forsworn fate then she will attack you on sight. This means you cannot use her Training option if you betray the Warsworn prior to encountering her.
She is in Mel Senshir, near the Sagecraft Altar.
Ney Csalan offers Master level Detect Hidden training if your current level is between 7 and 9.
She doesn't appear until after the quest Breaking the Siege.
Even if you are an enemy of the Warsworn, you can still sneak up on Ney and talk to her to receive the training before she attacks you.
