Tegin The Curator, a halfling treasure-hunter I met at the camp near Scale Gate, on the edge of The Grey in Wracklands, has finally admitted to being something more akin to a tomb raider or grave robber. He told me he has a new client, willing to pay handsomely for shissar tomes. If I acquire the tomes from within the Ruins of Ssraeshza, he says he'll split the take with me.
