Your mistaken, the Shaiya letters are nothing more than OS's logo with some photoshop work done to it. The text under the logo itself is nothing like Shaiya's logo text. To reproduce this effect all you need is some minor photoshop skills and a font you feel compliments the logo text as there isn't a public(or private i have seen) release of the font used to produce the logo. I suggest a Celtic font, there are thousands, as it seems this type compliments the text well. In the logo you pointed out it appears they simply changed the shadow color of the logo itself and mimic'd the color change in the text they added. The "sparkle" effect can be found using google images to search for such effects in an image form or using the brush tool in photoshop.
EDIT:
Here are a few examples of the logo edited in photoshop. This is released stock and open for editing.
