This is Yggdra as she appears in her cameo role in the new Sting SRPG, Gloria Union, a spin-off from the Union series of games that Yggdra Union started. I've tagged it appropriately, but I'm not sure how to designate a new tag as game or series tag, so if someone could categorize the gloria_union tag properly, it would be much appreciated.
For future reference, you prefix the tag with "copy:" or "copyright:" (minus quotes) for various copyrights. Same with "char:" or "character:", "art:" "artist:" or "gen:" "general:".
