Our story opens with the information dump to end all information dumps. There was a race that became so advanced that they created a interstellar gate system. Not only did it allow transportation to any planet in the galaxy - provided there was a gate, it also allowed for time travel. These ancient folk would tinker with the people on these planets, perhaps having been deposited there by them. Indeed, the universe seems very human through the books. They would change something and then jump forward in time a hundred years or so to see how that impacted the culture. Of course, they never traveled back in time, as that was clearly a path to ruin. However, eventually, they got close to the end of the galaxy and the only choice was to travel back and ruin befell. Now, onto the next info dump!
A mixed race of people, who were a fusion of the ancient race and humans, built a new civilization among the ruins but the gates were a danger. A team was assembled who would spend eternity shuttering the gates so that the disaster would not repeat. Morgaine was just one of these. While trying to close the Gate of Ivrel, the team was wiped out with the exception of Morgaine. She fled through another gate that jumped her a century forward on the timeline. To her, it has only been a minute. To everyone else, she was some mythic figure from a long ago battle.
Now, our story begins. Vanye was the son of a noble of one clan, but his mother had been a captive taken from a rival clan. As such, he was viewed as a lesser son, a half-breed. When he killed one of his half-brothers and maimed another, he was banished. This was essentially a death sentence. As luck would have it, he encountered Morgaine as she emerged from the gate. By custom, he became her indentured servant. The pair then set about closing the gate. The same man who had wiped out Morgaine's compatriots a century before was still in control. Could she overcome him this time?
The setting is truly outstanding and well-realized. Here is a variation on Stargate long before Stargate ever aired. Not only are the workings of this gate system gamed out in the opening chapter, the worlds that result have a mix of tribal people that repeat, showing how the ancient civilization mixed and matched to experiment. Vanye's mixed heritage plays heavily in the first book, as he and Morgaine are able to recruit assistance from his mother's clan. In fact, his cousin, Chya Roh, proves to be a recurring character in the first three books. Though the founding race was clearly high tech, this world is Medieval. Battles are fought with swords, spears, and bows.
Though armed with a dimension-ripping sword called Changeling, Morgaine is not some great warrior. In fact, she is more of a planner and manipulator. Her talents lie in recruiting aid to the cause, not in combat. She is also one of the few who understands the workings of the gates. By contrast, Vanye is a fighter, but he comes across as wishy washy. Always his honor prevents him from doing this or doing that. He has a lot of crises of conscience.
Back to Changeling, the sword creates a portable gate extending from its tip when drawn. Enemies can be swept away to who knows where? It is very effective but extremely dangerous. How does one sheath such a weapon? Not only can it sweep away enemies, it can function as an impenetrable shield as arrows and such will vanish into the void.
Highly entertaining and recommended.
