I am going through the Red Mantle Sash quest line and am at the step where I need to find the Terellian Ambassador that Sarithana Valran told me would be interested in the elvish books. I went to the Terellian Missionary by the Spellbinders Guild but he does not want the item.

I also tried giving it to the Terellian Emissary as part of the Rogue starting quest but they are KoS to me and I can't trade with them.

Has anyone been able to find this guy or know who they are talking about?
