Jemein Urthrin, called Jemein the Discoverer, is (or was) a travelling bard, and author of Travels in the Northlands, a copy of which is in the Enclave library. Travels also contains Jemein's poem in honour of Marcuria.
As he mentions in his book that Lord Ygvan Dellan is current Chief Council of the Ayrede Flag, and Vestrum Tobias tells April that Lord Dellan is still in office when she arrives in Marcuria, Jemein may have completed Travels recently and is probably still alive (unless Dellan is from a long-lived magical race.)
