Conjured Carriage

You summon a translucent carriage in a unoccupied space you can see within 30 feet. The carriage has no visible means of moving and is driven by a spectral humanoid figure with a perpetual scowl. Up to 6 medium sized creatures can fit at once, 5 in the back and 1 next to the driver. While summoned, the caster can control the movement of the carriage through telepathic commands to the driver. The carriage moves at a normal pace and ignores non magical difficult terrain it travels through. 

If a second carriage is summoned while the first is active, the first carriage slowly slips back into the earth in a slew of curses and complaining from the driver.
