Zank Rowan (ザンク・ローワン, Zanku Rōwan) was a Polynesian alchemist who was friends with Denkuro Togo and Nile in the 1700s, and an acquaintance of Dalton Strauss'. He was an Advenna Avis immortal, but was not listed amongst the surviving immortals in 2001--meaning that he must have been devoured by Szilard Quates.
