The C.S. Free Wind, it's proper designation, is a heavily modified Oceanhopper Class freighter. Oceanhoppers are outdated models, their manufacture being halted over thirty years ago, though dozens still take to the skies of Aurelia every day. Most are owned by transport companies that use the massive cargo bay to deliver various goods around the Crucible Empire, as the Oceanhopper was produced by Crucibellain shipwrights. The Free Wind, however, was decommissioned twenty years ago and was put on a backlog to be scrapped. Five years later it was purchased out of a junkyard by Summer Skies, who restored it to working condition and upgraded it from its outdated design. She replaced the old sails with a new advanced canvas that collects sunlight and installed power rails to hold this canvas and harness the energy to keep the thrusters powered. Though valuable and intricate these canvases are quite sturdy, having little worry of being damaged outside of combat scenarios. This design, commonly known as Solar Rails, is something that would not be common among ships for another five years after Summer installed it on the Free Wind. Due to these Solar Rails the Free Wind is surprisingly fast despite its size and weight, making only the most advanced ships of the modern age the only ones able to chase it down. Even older Interceptor class vessels cannot reach speeds the Free Wind is capable of at max power.

The Free Wind's original Aura generator is still intact and has been used as a back-up source of power, though it is still the original generator and thus very outdated. Nevertheless the Free Wind was ready for flight a mere two weeks after Summer acquired it. Since then it has received hidden armaments to defend itself. A total of a dozen aura cannons, six on each side, are hidden in the large cargo-hold below deck. They can be remotely controlled from the command bridge, positioned above the open deck. There are several cannons on the upper deck as well, though they cannot be remotely controlled and must be manually loaded with aura charges that would be brought up from a specific area of the cargo hold. The secret weapon of the Free Wind, however, is the Magnificant Laser installed underneath the bow. Being linked directly to the Aura generator, it can fire a massive payload of Aura in a large laser. This ace-in-the-hole can destroy many types of unarmored ships in one hit, though the fact it is linked to the Aura generator means it will take their back-up power source offline for an hour after firing.

As most of the space on an Oceanhopper class is dedicated to the cargo area, there is little room for comfortably holding crew. Without modifying the cargo space the Free Wind can only comfortably hold twelve people or so. The sleeping areas are split between three cabins, one dedicated purely for the captain while the other two are for men and women, respectively. Each of the larger cabins has three sets of bunk beds, allowing for up to six occupants each. To accomodate the crew's belongings there is an armory between the two cabins that has twelve lockers. The ship's only bathroom has two showers and two toilets, and it is located across from the armory for ease of access. Aside from the top deck, the command bridge, and the cargo hold the Free Wind is actually quite compact with narrow hallways and small rooms. Even the engine room that houses the Aura generator, located beneath the command bridge, leaves little room for navigation or maintenance. Even after weaponized the Free Wind it still remains a freighter that is largely dedicated to having a large cargo hold.

The cargo hold, taking up the majority of space among the bottom of the ship, is divided into separate areas. Along the sides it houses the cannons, along the roof at the bow it houses the Magnificant Laser, and underneath the laser is the room that stores the Aura batteries for operating the cannons above-deck. The center of the cargo hold is unobstructed to allow maximum cargo and use. More often than not it is host to a pool table in the back for recreation, and should the Free Wind take on a job to transport people there is plenty of room to set up cots to allow their "cargo" to sleep in the hold. There is much freedom in what to do with the vast open space of the cargo hold, but the fact the cargo hold is so big it leaves little room for the rest of the ship. Many guests have commented how such a large ship can still feel so cramped, though Summer Skies often takes that with offense.
