Add Effects to models

[Man of West Gondor]

I was wondering how do you add effects to models like let's say having a item glow like a flame, I know this can be pulled off by a tga texture and a plane polygon. But I'm not sure how to pull this off with Rome II. Dose or has anyone pulled this off In Rome II? I'm trying this to make this part of the book a reality in the game.

"Then the guards stepped forward, and Faramir opened the casket, and he held up an ancient crown. It was shaped like the helms of the Guards of the Citadel, save that it was loftier, and it was all white, and the wings at either side were wrought of pearl and silver in the likeness of the wings of a sea-bird, for it was the emblem of kings who came over the Sea; and seven gems of adamant were set in the circlet, and upon its summit was set a single jewel the light of which went up like a flame." (J.r.r Tolkien ~The Return of the King - Book 6 Chapter 5)
