This provides any of the expendable Glyph AA abilities.
Upon right clicking it in a main inventory slot, a new window will pop up similar to task rewards. You can choose from any of the glyphs available to you for your level.
Level 65 Glyphs include 1 bonus AA.
I'll edit/repost when my current character w/ the glyphs reaches 71 and 85 respectively.
*edit*
Comes from Legends of Norrath card game, mostly scenario rewards so far.
