Myriad Worlds: The ThestleBreak Shore
According to accepted historical record, the ThestleBreak Shore was first discovered by Duchen Yungus, the Bringer of Silk, on his journey to the north. Primary sources place the Duchen on the southwest corner of the shore, traveling north from the Dabadui river. Little remains regarding this discovery, and it is possible little concern was given to this aquanautical marvel. The traveling sages likely were not given time to explore the Shore, as sources claim the Duchen was in a hurry to reach Envik Klain, and continue his campaign against the Marauder King of Red.
Local lore, of course, places the discovery of the ThestleBreak Shore with the colonization of the continent by primitive travelers washed ashore, yet protected by the Shore itself. There is no evidence of this method of colonization, and little concern may be given to this theory.
