Black Panther. Uprising

"When T'Challa gets special permission to have his friends from America, Sheila and Zeke, come to Wakanda, he can't wait to show them his home for a change. But their tour is brought to a halt when one of T'Challa's peers, Tafari, summons dark forces in order to return Wakanda to the "old ways" before Vibranium was discovered. Tafari manages to banish the King and Queen along with all the tribal elders to an alternate dimension in exchange for the Originator's release, leaving Wakanda vulnerable and unprotected."-- Amazon.com
