“The Portmal” is the second book in The Order of the Sentinels tetralogy, The Eidolon Series.  This book picks up where the first book ended; at the Battle of the Kassam Pass.  Sentinel Stan stopped the hordes of The Collective dead in their tracks after he witnessed the death of his oldest son, Sentinel Ruben.  In his anguish, his Id seized control and unleashed the combined powers of the Paragon and Rummik, sealing the Kassam Pass in its entirety and bringing the mass slaughter he was witnessing to an abrupt halt. 

In his grief, Sentinel Stan vowed to never return to Mokiem and used his Xygar and Rummik to retrograde back to redeployment present time on Earth.  The remaining Mokaijem defending the battle zone quickly eradicated any members of The Collective who had made it through the pass before it was sealed. 

Book Two covers the actions of the Mokaijem in the week following the sealing of the Kassam Pass, as the odds they faced just became even more overwhelming with the departure of Sentinel Stan.  However, Book Two also extensively covers what happened to the Portmal, which contained the Paragons, Rummiks, and Xygars on Sentinel Stan’s redeployment present timeline.  The portion of the book covering all Sentinels in Sentinel Stan’s timeline will span decades, while also involving time travel to other centuries.
