There's been a lot of reincarnation s out there right? But there is one in particular that I really liked, it was about a princess of this country that was handed down this power from her predecessors. Not only that, she can contact her past predecessors AND the future successors of said power. She also keeps this power a secret as only the people who possess it knew about it, the power itself is kind of strange, she jumped off a tower and a gust of wind was strong enough to land her and her bodyguard safely on the ground.

BTW, these may be false memories but I remember some keywords and events: Lucia, Timothy, Legendary King, white doctors/ravens, and brothers.

AGGHHH This is killing me, please help!

I think it's Okoborehime to Entaku no Kishi.
