On the Dimhalt Road
The three of us walked onwards towards the entrance to the Dimhalt road. The opening gaped like a wound in the side of the mountain. I could see the fain glow of the tomb ahead. I do not know what Aragorn saw in the pathway but as one who could be the true King of Gondor his destiny lies along this road.
The rock was bear and arid, nothing lives here. This is the way of the dead and only the dead exist here. I do not want to come this way, the dead are probably responsible for the deaths of some of my kin. Their absence cost everyone dear. I do not want to deal with those who would break their oaths to their rightful king.
As we approached the the gateway to the path and the aura of death beyond; the horses tensed and then panicked. I could have calmed one horse down given time but now we didn't have time. Everything was conspiring against us. I let go of the reins and allowed the horses to return to camp. May they be of use to some other rider.
We passed through the skull surrounded gateway entered the mist filled cavern. For the sake of friendship I kept walking, I could feel the cold and the wrongness in the air. This pathway felt colder than the Pass of Carafess. I could feel the cold working its way through my clothes and skin. It was unnatural cold, the pain of those who had betrayed their oaths and the suffering of an age dead.
We walked onwards, Aragorn held Anduil ready. It was like a flame in the shadow. The sword was the symbol of the King, it was the one thing that would let us walk through these accursed paths and live.
