Lyza's Letter

Lyza's Letter is a piece of an unknown Artifact that has the message "At the Netherworld's bottom, I'll be waiting..." written on it.

Description
Lyza's Letter was among the other notes Ozen recovered from an empty makeshift grave made in the Garden of the Flowers of Resilience, together with Lyza's Whistle and Blaze Reap.

At a later point, it was given to Hablog, together with the other notes and the whistle, and brought back to Orth.

When Riko was given permission to view it, together with the other notes, at the Delver Guild HQ, she assumed this to be a message from Lyza to her and secretly took it with her.

According to Ozen, the letter isn't written with Lyza's handwriting, uses old Nether Glyphs without any simplified forms, is written in large and crooked penmanship, and not written on actual paper but an unknown Artifact.

Trivia

 * Even though the letter looks all worn out, it's very sturdy as even Ozen wasn't able to rip it apart with her strength.
 * The Manga text ends in "...", and the visual of the writing abruptly ending indicates the rest of the message is cut off.
