Bartellus was a Drenai herald during the outbreak of the First Nadir War. He served under Lord Abalayn.
Bartellus was sent to the court of the Nadir warlord Ulric after his brutal sack of Gulgothir to negotiate ongoing trade and peaceful Nadir-Drenai relations. Although Ulric initially seemed appeased, he asked that his shaman Nosta Khan be allowed to examine the omens. After a ritual in which a bird is sacrificed and its blood tasted, the warlord revealed his intent to go to war against the Drenai.
