Hehe, well i was looking trougth the game files, not something i do for fun xP  i was looking for a specific texture. Well any way i stumbeld upon 3 texture files Called labeled under Undercity but when i looked at them i was suprised, becase they looked like the same onld texture u find all over UC with one exception they were all icey and blue! :O
Well its not "Amazing" But i thougth it was worth posting, seeing how every one is crazy about every thing thats remotly conected to WotLK
And i Belive this is Since there is no ice in UC that i know of, and how "Undeady" the textures are, they would be a good texture in a Northrend Ziggurat or Dungeon.
If these allready are ingame, i apolagise, but if not here they are:
Edit: Found some... slime xD
If any one is interessted its the files:
And I am REALLY sorry if these are Used or been seen before
Could just be the ice texture of Naxxramas Real sry!!!!
