That said ...
After Mouse goes thru the SCUBA tutorial Gremlin leads you all to a beat-up ground van parked near the arcade. He has you wait a moment as he speaks with the arcade bouncer (who's not far from where the van is parked) and slips him a little something then returns and hands each of you a duffel bag. When Mouse starts to open it Gremlin says "Not here." He then leads you to the west (harbor) end of the New Harbor Mallplex. This is the admin complex for the mall and there's little foot traffic on the outside of the building. You then climb down a service ladder to a small nook with a security door at one end and another ladder down to the water at the other. Drafty, damp, and chilly apparently even the street people apparently find this area unappealing since no one is squatting here.
"OK, dry suits for everyone since we don't wanna leave a trail of wet footprints at our destination. You'll find a waterproof bag, put everything, even stuff you don't need, in it cause we're not leaving anything here." Instructs Gremlin.
As you all struggle into the gear you finally settle the question of Mouse's gender ... male. He's pretty androgynous.
Gremlin checks everyone's gear then ropes you all together, Chita in the lead, then you, Mouse, and himself last. "Hernando and Mouse keep an eye on each other cause I'm gonna be busy monitoring those sensors Chita placed yesterday."
With that the four of you descend into the harbor. Well ... you are dry ... pretty much, there is a bit of dampness around one of your ankles however. Since this is your first time underwater make a COOL roll (10+ to succeed) not to start hyperventilating.
You have no clue if you're swimming in circles or in a straight line, you sure hope Chita has a compass or something.
