When Vivec cured a sick farmer for free, he left an ash mask of his own face as a symbol of that statement. However, what fewer people know, is that he left a second ash mask in Gnisis as well - an ass mask. Out of embarrassment, the priests have hidden it away in the Temple basement, but those who find it can expect to receive a blessing for their efforts.
Okay, it's not actually terribly well-hidden, but it's definitely in the Gnisis Temple basement.
