Thunder Coach
Wondrous Item, Rare (Requires Attunement by a Creature with the Mark of Passage)
The Thunder Coach is the workhorse of Orien’s overland shipping, sometimes referred to as “galleons of the road.” A product of the Twelve, it incorporated members of Kundarak, Cannith, and Orien in the design. A typical coach is a 10-foot-wide, 40-foot-long, 15-foot-high (including the wheels) vessel of wood and steel. When pulled by a large team (typically eight tribex), a coach can maintain a speed of up to five miles per hour. However, if someone with the Mark of Passage attunes to the coach and sits in the driver’s seat, the full magic of the Thunder Coach comes into play. Under such conditions, four strong beasts can pull the coach at a steady pace of ten miles an hour. If it is moving along an Orien trade road, the effect is further amplified, allowing a top speed of 15 miles per hour. This requires the driver to remain seated and to maintain Concentration, as if casting a spell. However, beyond these limitations, they are capable of conversation and other actions.
The forward fifteen feet of the coach holds a small cabin for up to three crew members. The crew of a coach typically includes one marked driver and two crew members who serve as both guards and cargo haulers. One of these haulers is usually a Vadalis-trained (though unmarked) handler who cares for the beasts. The top of the coach has positions at the front and back where archers or wandslingers can be stationed with Half Cover.
A typical Thunder Coach has two cargo chambers; one magical and one mundane. The back gate of a Thunder Coach opens to grant access to an extradimensional space that functions in the same way as a Bag of Holding. When closed, the gate is typically sealed with an Arcane Lock linked to a password known to the driver. The mouth of the extradimensional space is 10-feet-wide by 10-feet-high. The size of the extradimensional space varies based on the model of the coach; the standard is 20-feet-wide, 15-feet-high, and 50-feet-deep. The system maintaining the extradimensional space takes up the final five feet of the coach.
Objects that produce extradimensional spaces (such as Bags of Holding, Portable Holes, or House Cannith's Crates of Containing) cannot cross the threshold of the rear compartment. For this reason, and to allow the transport of living creatures, the Thunder Coach also has a standard cargo compartment accessed from the side of the vehicle; this space is 10-feet-wide, 10-feet-high, and 20-feet-long.
