Gosok Skyborn
The mul finds that writings on the floor are forming two circles around the broken column, each circle written in a different language. The inner circle is written in runic language identical to the one he uses for his own purposes. While the formulas used within are much more complex than anything Gosok can muster the context of the writing is fairly clear: it's a spell to magnify and channel the power of the column... or more likely an object placed in the column to affect a specific nearby area. Well it was a spell anyway, now it seems inert.
The outer circle is more difficult, trying to understand those writings makes Gosok's eyes water and gives him a slight headache but finally he begins to understand what he's looking at. It's a set of symbols forming phrases in an advanced form of Primordial language. These words seem to be a combination of words of power, probably intended to supply the rune-spell made with inner writings; and symbols that should ward the area off for mortal beings. Alas parts of the outer writings, mostly of the wards are damaged - the floor they were scribed upon gave away under the hand of time.
Berak
The shardmind does find another way out of the room, a wide passage in the left wall (that couldn't be seen when looking into the room from a distance and most certainly not one I forgot to mention when first describing the room) that ends with a set of solid double doors. As for magic, there are traces of it in the chamber but it's just that... traces.
Isirius
On a closer look the "column" seems to have a hole drilled in the top of it, enabling one to place something in it. Like a torch or another object of similar shape.
