My main character in Virus is Ruiz. He is a janitor/garbage man/electrician who works within the Hub. He's been there since early on, works well with the children and is known to just about everyone.
I also am available to NPC Mala and Denisa, who are two children who, in our timeline, had been part of the Lighthouse Kids.
I will also be NPCing a character named Shanna, who works with the Hub from a medical standpoint. (though she was a chemist, not a virologist!!)
Also— Gillian Childs is taking on her role of the McGuffin (McGillian?), that prized item that everyone seems to want to get their hands on (cause in this case her ability might help Magnes and Liz get the heck out of this horrible place), though she won't physically show up (she is NOT in the Hub and never has been). Those who wish to have known her before the Virus and the Hub, please contact me.
