Adair River Span is an ancient oak treefolk of Lorwyn. As a monk, Adair chooses not to wield any weapon, instead using his fists to fight those he encounters while roaming the plane seeking to prove his battle prowess. He is especially fond of fighting giants, of whom he once defeated two at the same time (one with his fists, the other with his caustic insults). So robust is Adair that, on a bet, he once drank the entire Honeystone River dry all on his own. He has amassed a great number of folktales around his person in his countless years of wandering.
Adair was a good friend of the ash sage Flann, and is currently seeking her out, unaware that she has been killed.
