Eric Swan is an agent with Q2.
The blurb I read for the first recorded adventure stated "Eric Swan can be killed - but he can never die. For a government agent hunting the most dangerous domestic terrorists, that comes in handy." With that as the introduction to these stories, how could I not check it out.
There is an origin short story available about Swan and it does explain how this Special Forces operative came to be moved from the U.S. military to working for Q2 under the direction and highly critical eye of Quanta. That person is described by Swan as "a short Asian woman" whose "age was hard to pinpoint but her body was lean and strong, her movement graceful, and her eyes intensely sharp. She was either looking at me or through me." The one word that Swan landed on to sum her up was "formidable".
We learn in this prequel story that Swan comes from a background that contained some "tragic losses" that he refuses to talk about. His life in the military has helped him survive and given him a cadre of compatriots that he enjoys working with but by and large Swan is used to working alone and he is good at it. He is also good at getting the job done which is why Quanta and her Q2 outfit was interested in him and therefore recruited him after an introductory mission to see if he could cut it. He did.
But now back to the opening blurb and the comment that Swan can be killed but cannot die.
Explaining much more would very much take away from the pleasure of learning it yourself through reading the adventures. I will leave it with the fact that the technology that Q2 has developed, Swan is able to take part in a good number of harrowing escapades, each of which he will do his best to pull off without loss of his life. If, however, that should prove to be not possible, there is always next time.
