The land of both Tethe'ala and Sylvarant put together make up the world of phantasia as seen in Dawn of the New World. Locations like Mizuho Village and Ninja Village are related to each other and the new descendants of the Fujibayashi family can be seen in Phantasia. Summon Spirits and locations like Ymir Forest, Heimdall, and Treant Forest are found in both games. ORIGIN can also be found in the same location in Symphonia and Phantasia. The naming of the world tree in Symphonia is meant as a nod to players of Phantasia who know the True name of the Tree is "Yggdrasill" in Phantasia, referencing Mithos Yggdrasill. Dhaos, who is now the leader of Derris-Kharlan in Phantasia, knows about the use of the Mana Cannon that was used in the past, which he could of learned from "Kratos" or from what is left about it on Derris Kharlan.
