Codex Regius

A mysterious race from an alternate universe has allied itself with the Jotunn, and the alliance is set on destroying the Aesir and bringing about Ragnarok. With an ability to jump between universes and unstoppable time-based weapons, the Efreet seem invincible. The Vella Gulf is the only ship to survive its first meeting with the Efreet…but only through a fluke of luck. Worse, Lieutenant Commander Shawn 'Calvin' Hobbs has just found out the Efreeti home world is the same planet in their universe as Terra is in ours. If true, the Efreet could cross into our universe at any moment and annihilate the Earth without any warning. Terra lies defenseless! Calvin and the crew of the Vella Gulf have a surprise for the Efreet, though; they have returned to Terra with the ability to cross between the universes like their enemy. Armed with personal transporters and jump modules for their ships, they're now able to take the fight to the Efreet. But will they be in time to prevent Terra's annihilation? As the Efreet continue their inexorable onslaught on all fronts, Calvin only knows one thing. The answers to all of their questions lie beyond the shroud of the universe.

It's victory or death for humanity! The war with the Shaitans continues, and Lieutenant Commander Shawn 'Calvin' Hobbs has stayed behind to help the reptilian Ssselipsssiss race fight the Shaitans while his ship, the TSS Vella Gulf, has gone for aid. Formerly enemies, Calvin now finds himself supporting the Ssselipsssiss in their war against the Shaitans in a "must-win" situation. If the Ssselipsssiss fall, Terra is next! Able to operate in two universes and armed with unavoidable time-based weapons, the Shaitans have proven unstoppable. Although Calvin has experience fighting the Shaitans, the Ssselipsssiss are down to their last three planets, and Calvin's assistance may very well be too little, too late. The only ship with any success against the Shaitans is the Vella Gulf, which can jump to the Shaitans' universe and fight them on their own turf. But time is short; will the crew of the Vella Gulf be able to find the mysterious "Dark Star" system of the Shaitans and stop them before they destroy Terra? Faced with an implacable foe, the Terrans have been forced into an alliance where the enemy of their enemy might be their friend…or might not. The crew of the Vella Gulf will have to choose their allies wisely as the stakes are the highest possible-only one race will survive the Dark Star War!
