Record that Gets Buried Again

I read everything on the Ancestors' Stone. Now the stone is useless. But we can't throw it away anywhere. Things from the earth should go back to the earth. This stone will be buried again according to an Elf ceremony.
To make it happen, I need to ask you a favor. I need to bury the stone under the tree in the <HFFFA7272>Upper Garden<HFFFFFFFF> of <HFFFA7272>Salarmis Garden<HFFFFFFFF>. Please kill <HFFFA7272>30 Centaur Archers<HFFFFFFFF> who appear there. They really hate to see their land being altered.

You didn't understand? I want you to go as soon as possible…… Please kill <HFFFA7272>30 Centaur Archers<HFFFFFFFF> in the <HFFFA7272>Upper Garden<HFFFFFFFF> of <HFFFA7272>Salarmis Garden<HFFFFFFFF>.

I arrived safe and sound, thank you. It was a joyous occasion to have met my ancestors, even for a short time. Sorry? What am I talking about? Hahaha. I can't tell that to anyone, not even you. We're only the messenger of the Elf's. Anyway, I owe you a big one this time. Just let me know if you need any help in the future. Thanks for all of your efforts!
