So I'd like to introduce E13 in the story in a way to get them involved. I have a few ideas. 

The first is that they were hidden in the Venus District, and Hiro just stumbles across them on his mission to go speak with Sweetie. Probably he would spot something out of place, and when investigating, accidentally open a secret compartment. 

The second idea, if [@Eviledd1984] is amenable, is that someone at YZ got an inkling that there was more to Cadmus's project than what she turned over, and their mission leads them to find E13(and I cross my fingers that Maggie decides not to turn them over). 

Thirdly, again if [@Dark Cloud] is interested, they get out by some fluke, and Sanguis sees them wandering the Venus district and tries to kill them, but discovers it's more difficult than expected. 

But if anyone else wants to collaborate with me as well, just let me know.
