I quickly checked the topic below, but didn't find anything just searching for 'orc'.

EASTEREGGS and RUNE manuscripts
Note: Kiya's web host changed some time ago, but any old links to 'kiya1.via.t-online.de' just have to have the '.via.t-online' deleted to work properly.


If there is an image on the manuscript, see if it is listed on this page: Divinity Runes.
