Rock Ōtsutsuki's Stone Tablet

The stone tablet (石碑, sekihi) is a monument which was created by Rock Ōtsutsuki in order to discourage his brother; Indra's descendants from attempting to recreate the Rinnegan. The tablet can only be deciphered fully by the Rinnegan, while the Sharingan and Mangekyō Sharingan are able to partially decipher it.

History
Before Rock's father, Hagoromo Ōtsutsuki's death, disguised as an elderly beggar woman, the Enchantress went to the Land of Ancestor's palace on a cold winter's night (and possibly stormy, due to the presence of lightning and elements of rain on the stained glass windows depicting the event), and she asked if she could stay overnight to be protected from the cold in exchange for a beautiful rose she was carrying. Inspired by the beautiful gift and her appearance, Rock let's her in in secret only to see the loss of Rock's father. As Rock cries and mourns to his father and his brothers when he see his brothers killed by each other, she revealed her true form to him.

Seeing how powerful she was, Rock sees the loss of the elderly beggar woman she loved, but the Enchantress forgives Rock by letting him see the future and the stone table was placed in the mushroom kingdom before the fourth pescan war, certain details on the tablet were forged by Enchantress. In addition, she also gave him a time limit that would enact upon his twenty-first year: After that period, the enchanted rose, which will have fully bloomed by then, will start losing petals, and if the last petal fall after the Enchantress comforted Rock's loss of his brothers.
