Meet the Diamond and Pearl Clans of Hisui regions, and traders from the Ginkgo Guild. There’s a lot more to discover on #PokemonLegendsArceus!https://t.co/WI1CBeipt4 pic.twitter.com/uuuz4dHd6op. Pokemon (@Pokemon) December 15, 2021. The trailer officially introduces the Diamond and Pearl Clan, two groups that live in the Hisui area, too. According to the official description of the Pokemon Company, “the people of the Diamond Clan often speak of the importance of cherishing the present and living in the moment with allies. Members of the Pearl Clan often advocate for the value of vast, vast land shared with others.” Diamond and Pearl Clan have both new NPC leaders, each of them having a Eevee evolution as a partner Pokemon. Adaman is the leader of the Diamond Clan. Leafeon is his partner. Notably, Adaman “hates to see time go to waste” refers to his clan’s desire to wear clothes that look like Dialga. In the meantime, Irida is the father of a pearl party, and the partner Pokemon Glaceon is the co-owner. Irida believes it is important “to have the courage to face the vast Heui region,” a reference to Palkia, which is related to space. Both of the leaders have an interesting stone around their neck indicating a possibility that they can summon their respective Legendary Pokemon or perhaps unlock a new form. In addition, a faction in Pokemon Legends was introduced: the Arceus trailer, the Ginkgo Guild, which seems like they have related to present-day games. Two of the merchants shown in the trailer Adamar and Volo seem to be the ancestors of Volkner and Cynthia, two prominent NPCs in modern day Pokemon games, set in the Sinnoh region. Pokemon Legends: Arceus will be released on January 28, 2022.
