Foul Play

Yesterday, a 7-day celebration of Harvest Week began in Azeroth and players were able to discover one of the new little secrets of the Battle for Azeroth add-on, added in update 8.2. During this event, the tauren, who have completed the necessary requirements and completed the quest chain, received the traditional Shu'halo Legacy armor of their race, a small secret mission is available.

If your tauren has traditional armor, then on the days of Harvest Week at Spirit-Master Usso, which can be found in Durotar at coordinates 48.8, 15.5, you will be able to use the "Memory" task. In this quest, Usso will ask you to honor the ancestors who reported the impending threat and helped protect Thunder Bluff from a recent ghost attack by making an offering to them. To do this, you will need to go to Mulgore at coordinates 33.9, 38.6 and lay gifts to the fire on the mountain. After that, the ghost of Leader Tachuk will appear, who will thank you for following the traditions of tauren and honor the memory of your ancestors.

Chief Tachuk: <name>, so we met again. I see you continue to follow our ancient paths.
Chief Tachuk: Our rituals and traditions serve a sacred purpose. They maintain a balance between our worlds.
Chief Tachuk: Every tauren must observe these rituals. Spirits expect us to fulfill this ancient duty.
Leader Tachuk: My heart is filled with joy when I see all your accomplishments. I look forward to your next adventure.
Chief Tachuk: Until we meet again, brave <name>. May Mother Earth protect you.
