YOU SHALL NOT PASS!

Journey to the part of the Doxon Duchy the tomb was located was in two parts.
They used teleportation circles to cover a majority of the distance and arrive at the closest city to the tomb but as the city was not a stone throw away from the tomb, they border a rented carriage that was more than large enough to fit their party of Nine...
(Hal, Emily, Rita, Karmen, Olivia, Lillian, Andrei, and two capable guards he brought along with him. One named Jared and the other named Harold)... Excluding the carriage the driver of course.
The carriage was quite speedy and in a few hours, they were closing in on their destination when the carriage suddenly stopped with the driver claiming,
"This is as far as I go. Beyond this point, the carriage won't work."
No one thought of this as ominous. If anything, it was a tad expected that there would be procedures put in place to prevent the disturbance of a final resting place.
