Akiol tossed the strange triangular coin of the Abyss. As a gift for their foreign prince Akiol was given a small humble sum to spend on things to purchase in the Abyssal Cities. At first he intended to refuse, until Dimitrin insisted to come along.
It seems this was another test. One while Flinnder and Dot were handling other matters until the Royal competition.
So he accepted the small sum with a humble attitude and brought Rue along. With Dimitrin's presence he didn't have to worry too much about any outsiders trying to attack them. As for what he was supposed to buy, perhaps some artifacts regarding the Abyss for Kan'na to study?
Materials weren't really needed. There was no one besides Kan'na who could utilize such materials. Tilia, Yielya, and Jarvis had completed their new set of equipment if the images in the group chat were to be believed. Akiol certainly did not need such materials. As for Wrock. . .
