Cassie Parker is a thief.
Remy Tambook is an agent with the Dread Nought Corporation.
The two worlds in which Parker and Tambook reside are wildly different and there is no logical pathway that would take one into the other's orbit - until it did. But I said logical and even Parker would admit that what she did when she did it was not in the sphere of logical. When she saw a van pull up a bit in front of her on a city street and black-masked fellows leap out to snatch up a young woman, she did something she would have bet she'd never do and got involved. I mean, really involved as in taking on a couple of the would-be kidnappers with the skill that she gained over the years in self-defense, although this was more in the line of offense. Meanwhile, the almost kidnapee, whom we learn soon is Tambook, was not just standing meekly by but was ably taking care of a couple more assailants. Within seconds, four guys are prone on the sidewalk and Tambook is leaping into the van and pulling Parker in with her and tossing the driver very unceremonially out and taking off, stealing the van the men had planned to use to steal her.
Parker is a bit dazed, first at the fact that she went against her nature and did a Good Samaritan act and then at the fact that Tambook would turn to her and call her by her name. As far as Parker knew the two had never met and yet ... One impulsive act will change both of their lives.
This is all told in the very first pages of the very first recorded adventure. After that, things get a whole lot more exciting. This is shown in part by a tagline for the first adventure, "Save the World? Or Kill Each Other? Tough Choices".
And now a brief moment to talk about Dread Nought (yes, the spelling with the 'o' instead of 'a' is correct here). The company is a privately held intelligence collection and black-ops conducting organization working on behalf of ... well, that sort of gets confusing. As Dale, another key player in these adventures, asks himself, "Was Dread Nought on the side of the angels? Was it the right hand of Satan? He knew neither of these simplistic depictions covered the truth. A more nuanced question beckoned. Did his company do more harm than good?"
This ambiguity makes the things that Parker and Tambook get involved in even more interesting. And then it got ... well, different!
