Wierd Gw Text

If this is in wrong place i appologise and a mod can move to corret section.
Heres the question - whilst farming in melandrus hope on the 55 n/mo build i recieved some text that was unexplainable on that chr but my 2nd account which was present only had the Ha message.
The HA text came up as usual on the necro but below it in same font and color was the following "i am a stone.i do not move.i do not tremble.i have no fear"
Has anyone else ever had this or does anyone know why/how i got the message or even what it means.
