The Darkhaven Carriage.
Carriages within Revendreth are a method of free transport, driven by Cudgelface and pulled by two sinrunners , that run on a fixed circular path back and forth continuously. Jumping onto a carriage disengages from all combat and makes you untargetable by NPCs. You can embark and disembark at will.
