Funny Sorcerer dies, but revives, but finds out there have been buffs while asleep. Also, everyone calls her Tabby cause that's what her names sound like basically.
In Kiki's world it's not too uncommon to find a few Wizards or Sorcerers from the "Wild Age" of magic, where some of the most powerful of Magi users would enslave, control, or rule over a territory. Most times these people would be killed or die of reasons but sometimes they set up contingency plans, often in the form of Revival.
Tabby used to be an Evil Empress who wielded dark magics to enslave and control a small nation to do her bidding (Build statues of her, fan her, write poems about her, and other trivial things) but when she died she was determined to come back stronger than before by slowly gathering magic in her revival jar. It worked! Though when she woke up 1,800 years too early she found out things had changed.
While she was "Powerful" she wasn't exactly on top of the world anymore, more to the point, she was out gunned and out of her elements in this new world where Magic had been tamed. She had gone from, "Evil Empress gunning to control the world" to "Normal".
