Erika was right. A small group was probably best to maintain a low profile and not get caught. However, there were multiple objectives here beyond the library.
Ange and Erika were already wearing clothing that modern earth would be accepting of; Kiritsugu also already seemed to be in clothing befitting of it, along with Ash.
However, as it was having a team larger then say, three people would be dangerous.
Multiple objectives called for multiple teams. There was also culture shock to consider here; some people may not even recognize a car or its functions, either because they're far to advanced or behind in technology.
With that, the Witch of Truth began outlining her reasoning.
"Kiritsugu, Nova, and the man in armor(Charr)." You three seem to have military experience. Why don't you go find out about this eras weapons and technology. These "Knightmare Frames" seem particularly important. If you could somehow bring one back here and in one piece without arousing suspician that'd be fine, but at least seeing one would confirm many things."
Now, on to the library and information gathering group.
"The man with a metal arm, myself, and Erika should try to find a library and gather general information about this world."
Now, on to a trickier part of the mission.
A girl had said she could make it so others could not see her. That was excellent ability that would help them, much like the other girls ability to turn invisible.
"You're the girl who can manipulate peoples subconscious, right?" Ange spoke to Koishi who seemed to appear once more.
"I'd like you to find someone and bring them back here. Be careful and don't risk to much, and most of all don't get caught or alert others to our presence. We can use them as a means to gather more information as we need it."
On to more tasks to be designated.
"Girl with the guns(Jo), I'd like you to scout out the area around us along with Mephiles. Keep track of anyone who enters and exits this entire area. If anyone attacks, you need to warn those still here. I'd also like you to look for any easy escape routes, above and below ground. If the sewers are large enough, we can use those to escape with our allies from Cybertron if we must run."
And finally, the all important job of their base.
"Everyone I didn't speak of(For the most part the "Warriors of Cybertron", who seemed to be more aligned to wrecking their enemies in direct combat), please try to sort through everything here and prepare defenses for the warehouse. The "warriors of cybertron" can perhaps start digging a large enough tunnel into the sewers or something to that effect, so that we may have a chance to all escape if need be."
Well, that was finished. Still, there was one last thing. . .
"Everyone, try not to telegraph your presence. If you do intend to let people know we're even here, make sure to silence them forever or bring them back here to store. We cannot let others know we're here this early on. Don't have your weapons out among the public, and try not to make scenes.
Also, if anyone can find devices we can communicate with, that'd be useful. I don't want us to be cut off from each other in the event something goes wrong."
