He arrived on Gielinor recently with several other ilujanka from Iaia. Carthalo has been teaching Mr Mordaut about the history and culture of the ilujanka, and he in turn has taught him about the culture of Gielinor. Carthalo finds the celebrations on Gielinor fascinating, stating that they are very different from those held in Iaia.[1]
Carthalo mentions an alcoholic beverage called Redcane rum during the Heartstealer quest.
^Carthalo, "Heartstealer", RuneScape. "I hail from Iaia, the homeworld of my people. I arrived on Gielinor with several of my kind only recently. I have been teaching Mr. Mordaut about the ways of the Ilujanka, and our history. He in turn is showing me the culture of Gielinor, such as this 'gala'. [...] It's fascinating. Very different to celebrations back home."
