These foreboding lights will shine in our night sky like new stars, getting ever brighter until they outshine even the sun, casting ominous shadows and banishing the night until they suddenly blink out. Their technology is vastly superior to ours, and they know they cannot possibly lose the coming conflict. But they, like us, have found no answer to the destructive force of the atom, and they have no intention of facing the onslaught of our primitive nuclear arsenal, or the devastation it would wreak on the planet they crave. So they have flung out an advanced party in front of them, hidden within one of the countless asteroids randomly roaming the void. They do not want us, they want our planet. Their Agents are arriving.

Crossover


Joel Shepherd - 2001

She deserts the League and heads incognito into the space of her former enemy, the Federation, in search of a new life. Her chosen world is Callay, and its enormous, decadent capital metropolis of Tanusha, where the concerns of the war are literally and figuratively so many light years away. But the war between the League and the Federation was ideological as much as political, with much of that ideological dispute regarding the very existence of artificial sentience and the rules that govern its creation. Cassandra discovers that even in Tanusha, the powerful entities of this bloody conflict have wound their tentacles. Many in the League and the Federation have cause to want her dead, and Cassandra’s history, inevitably, catches up with her. Cassandra finds herself at the mercy of a society whose values preclude her own right even to exist. But her presence in Tanusha reveals other fault lines, and when Federal agents attempt to assassinate the Callayan president, she finds herself thrust into the service of her former enemies, using her lethal skills to attempt to protect her former enemies from forces beyond their ability to control. As she struggles for her place and survival in a new world, Cassandra must forge new friendships with old enemies, while attempting to confront the most disturbing and deadly realities of her own existence
