Iron Fist was still smiling as he pondered what sort of scenario to set up. It should be something to properly test the Titans stealth skills while being flexible enough to adapt to anything they tried to do or for that matter failed to do. Not to mention he wanted to have a little bit of fun with them first off and make the training memorable for those involved so it didn't come off as too harsh while not fading from anyone's memory any time soon. Eventually he decided on an amalgamation of some of his own experiences would best convey why the necessary skills were so necessary. He moved up to the observation deck and punched in the scenario he had in mind before announcing it over an intercom.

"Let's see. I think you'll all like this one. A little something from my personal file: The Castle of Nightingales."

With that the room began to fade away, replaced by a soaring series of pagodas dappled by soft moonlight. There were even crickets chirping in the background and the soft dripping of water from somewhere, in fact there was very little to indicate anything other than a peaceful night. directly behind Iron Fist a sliding screen door lay open with a vast hallway leading to a set of stairs that in turn lead to another hallway. Occasionally a guard in the sort of clothes that suggested a kabuki stagehand or stereotypical ninja would patrol set routes before turning around again. Interestingly their faces were completely covered, leaving no room even for eye slits. No torches or lighting illuminated the interior either.

"Welcome to the Castle of Nightingales, Titans. Your objective in this scenario is to sneak through this fortification and meet with the informant held captive at the very top of this its' tower. The guards inside are actually blind, but don't let that fool you, they're all highly trained professional killers who are more capable without their eyes than many warriors are with them. Moreover, if you fail to take them out quietly and attract the attention of too many, there's a dangerous surprise waiting for everyone. Work together and remember: the key is to think and move as one with both your environment and your enemies."

It wasn't actually that simple of course. The truth was that the floor was boobytrapped so that if anyone stepped on it carelessly or in the wrong way it would send up a sound like nightingales singing, which attracted the attention of the blind guardsmen. the guardsmen themselves were also actually androids underneath their masked faces and were more resilient to damage than they seemed though in this case he'd set it so a proper stealth attack would take them down easily. That said, he hadn't known those things going in, and the stakes were a lot lower for the teens in his care than they had been for him. As for the surprise, well, it was supposed to be more of a "game over" occurrence, but he was looking forward to seeing how they handled it.
