This is a fanfiction centered around an Alternate Universe Marathon-class Cruiser being somehow transported to a new Universe by a mysterious Precusor known only as the Timeless One. Could this universe spell salvation for a lost crew or damnation? Earth is burning, shadows are moving and an ancient threat has awoken.

Marathon Class Cruiser, UNSC Mercury
The UNSC Marathon-class Cruiser is the forefront of the United Nations Space Command’s Naval Arm, incredibly expensive to build and a valuable asset to any fleet or battle group, the Marathon class is only given to the best commanders. Since the battle of Psi Serpentis and the subsequent discovering of the Forerunner cache the Marathon class has gone under several upgrade phases.
The Marathon class cruiser originally boasted 2 Mk4 heavy MACs, seventy oversized archer pods, and 35 50mm CIWS guns along with 7 meters of Titanium-A plates. The upgraded cruiser boasts 2 Mk8 Heavy AHR Cannons and a Mk7 Light AHR gun on an underslung turret as well as a CIWS suite of 50 50mm Rotary Rail HE CIWS cannons and twenty seven 500mm Coil Gun turrets. Seven meters of composite Titanium-B/C layers and ARC armor on a Titanium-B/C honeycombed hull allows it to absorb ten plasma torpedo impacts on the same site without significant damage. The new inertial dampeners reduces the relative mass of the ships enough to allow the Marathon class to match the acceleration of the faster Halcyon class cruisers. The Mk8 cannons can fire two consecutive shots. The Mk7 light MAC can turn 360 degrees by 30 degrees and are capable of three round bursts as well as sustained standoff slug fire at ten rounds a minute. The seventy Oversized M-58 Archer Pods have been refitted to fire Longbow and Javelin missiles. Forty Harpoon torpedoes are the standard load for the cruisers and the Mk8 cannons can each fire a spread of 5 Harpoon with enough energy left for a standard heavy slug.
The UNSC Mercury holds 24 GA-TL1 Longsword Strike Fighters, 12 MBT-982 Ravager Main Battle Tanks, 48 M12 LRV ‘Warthogs’, 18 D77-TC Pelican Drop-Gunships, 10 M-81 Cougar Infantry Fighting Vehicles, and 4 TAV-551 Fox Self Propelled Heavy Artillery and 2500 UNSC Marines with a platoon of UNSC Orbital Drop Shock Troopers.
Electronic Warfare Suite
In order to counter the sheer power of covenant weaponry, UNSC Naval Weapons Division sought to neutralize it instead of withstanding it. To that end, vessels equipped with a Electronic Warfare Suite (EWS) utilizes multiple means to hide from or blind the enemy. The suite utilizes cold plasma fields surrounding the entire vessel to absorb the EM energy of covenant radar. Any residual reflected radiation is then interfered with and its information distorted via erroneous return broadcasts. The result is that while the presence of a vessel using the suite is still detectable, its exact location, profile, and velocity can not be discerned accurately enough for an accurate sensor profile and weapons lock up to a certain range; even within that range, there is still a certain distance where weapons fire cannot be targeted on individual systems and damage is based purely on luck. An array of high power masers scrambles short range electromagnetic sensors and communications of the enemy, greatly degrading their overall combat capabilities. The main weakness of the EWS, however, is that it can be countered by seraph fighters acting as scouts relying information to covenant ships. Though this can be alleviated by the point defense suite, friendly fighter cover is the best counter. The Mk 1 EWS is a starship grade suite and equipped on all vessels. The Mk 2 is made for Longsword-B interceptors and Spitfire class corvettes.
Star Drive overhaul
Covenant magnetic confinement and slipspace technology has been successfully combined with UNSC reactor technology to create a potent star drive system. For the first time outside of experimental reactors, Helium-3 is now used as the secondary fuel supplementing the deuterium/tritium mixture currently used. As an neutron fusion fuel, Helium-3 provides a far higher efficiency and output but imparting the vast majority of its energy output in the form of high speed protons that can be easily harvest for energy. The challenge in the past has been to achieve the far higher temperature necessary for Helium-3 fusion without suffering marginal loss in efficiency against standard deuterium/tritium fusion. That obstacle have finally been overcome by the marriage of UNSC multi-reactor boosting and refined Covenant magnetic confinement technology. The main reactor will normally run on D/T fusion, but can switch to He-3 fusion during combat with the help of the tertiary reactors. The new reactor upgrades will double again the original gain by the multi-reactor boosting technology obtained alone. Combined with superior Covenant inertial dampening technology backwards engineered, UNSC ships with the full modifications can achieve anyway from 48 percent to 122 percent boost in acceleration depending on the tonnage of the ship.
M768 Armor Piercing Hollow Point Slug
This APHP slug is only half the size of its predecessor so as to increase its velocity and probability of impact, though it deals significantly more damage. The round uses uses a traditional hollow point design, using a nickle steel jacket that would mushroom and damage its target far beyond the impact site. Should the target’s armor or shields prove too strong for the nickle steel jacket, an interior self-sharpening tungsten kinetic penetrator will concentrate the remaining kinetic energy for greater penetration. Depending on the size of the target, the round can completely fragment with a shotgun-like effect that could tear whole sections of the ship off; the bigger the ship is, the more destructive the round becomes.
