It is good to have a wide range of ships plying the space lanes, so this is an interesting and unusual craft to add to the mix. Repurposed from a military vessel, the T-C-300 Freighter was (officially) disarmed before being sold on although, life in the black being what it is, many merchants have mounted weapons of their own after purchase. Alas, some pirate, ahem, ethically challenged merchants have picked up these ships as well.
The ship is very manoeuverable in open space, with the drives being mounted in the three pods that are the distinctive feature of the design. However, they are not able to operate in atmosphere and may encounter difficulties in extreme gravity wells. Many spacefarers find these ships quite threatening, as you cannot tell what sort of weapons they have mounted (if any) until they power up and open fire.
In this product there is quite a bit of background about this vessel, nice external views from several angles and deck plans, also a full stat block and example captain and crewman stats.
A useful addition, be it something seen in the space lanes or a vessel your party may wish to use themselves - crew accommodation appears limited to four people, so larger parties may find it a bit cramped, however.
