Here you go this is the translation of the wall if i am not mistaken

Het Nok Faal Vahlok
Deinmaar Do Dovahgolz
Ahrk Aan Fus Do Unslaad
Rahgol Ahrk Vulom

Here lies the guardian
Keeper of dragonstone
And a force of unending
Rage and darkness

Hijagi gave the correct word-for-word translation, but there's a bit more to it. The word "the" is often omitted in the Dragon Language, so the official translation (as shown in the Prima Official Game Guide Legendary Edition) is as follows:

Here lies the guardian
Keeper of (the) dragonstone
And a force of unending
Rage and darkness
