Anyway the usual..I'd like some full-reads but will take comments on the begining as well, especially if you dont mind talking about it. The whole thing is about 5k.

Your first two sentences are written in a passive structure - I suggest you make them more active. I would avoid words such as "had", "of the", and "come", and suggest you use more active verbs. Active verbs are an opportunity for description, without bogging the reader down. For instance you could write:

"After months climbing the steepest mountains, traversing across the wide desert plains, and crossing two seas, Lightmaster Aronos and Zorthas the Dimensionist finally stood before the Ruins of Vorestos, legendary gateway to The City of the Night."

Tall crumbling pillars and enruned plinths of stone stood all about them beneath the darkened sky, some bearing markings that even the two mages could not decipher.

This paragraph could be reworded to be more active as follows:

They strained to read the runed stone plinths encircling them beneath the darkened sky, but could only manage to decipher a few.

Okay, that was terrible, but I hope you get the idea.

The idea I want to convey to you is to use active structures and active verbs in your writing, because that will suck the reader in and you will be showing and not telling. (This is a goal I constantly strive towards.)
