eyes of intrigue - let you 'look' at a room that the target was in. cost ~80mana to use. You could use it nonstop.

fade = hide. If you had inherent sneak (dark-elf) you could stay hidden while moving. You could make an charmie in the game fade at one time. order all fade;or all sneak

shadowgate - took you to the 'plane of shadow' or something like that, which was a very small area with exits to different spots around Thera. It was a way to fast travel. I think it also had a backdoor into the cabal for defense.

nightwalker - let you create a nightwalker which was nothing like current nightwalkers. It was just a merc.

Don't get seen with a nightwalker, don't get seen stepping out of the shadows if you couldn't hide. If you did it would be confirmed you were shadow.

Inside the cabal you were a 'cloaked figure' or something like that. Over CB you had an alias.

It's been a long time so I might be missing something. But all that mattered was eyes of intrigue.
