Anyone else gettin +exp bonus from leveling their cygnus?

Hey guys, just curious if anyone knows if there's some event or something for cygnus chars. Reason why i'm asking is because will leveling my dawn warrior today, i noticed that upon the huge green *LEVEL UP* i get when i level, i also get a *+EXP* in blue that gives me 10% upon leveling up. It's not a big deal or anything, just kinda curious why its happening, i can post a ss if needed and stuff.
