These are artifacts from Yenak. Y-1: Seems to be a snippet of some sort of song. Contains some perhaps musical references below? Y-2: Seems to be a sort of scripture. Differences are found in the word structure above and below, with a bracket separating the two. This time the below section seems to be syllabic in nature. Y-3: Depicts some of the Inputs with some names. Likely in the native Yenak language.
It is likely that the author of these fragments used some sort of language Tosefteh brought, likely from the Semitic family. (The shards are found in Omlobar after the timeskip. You can try to solve it now! I will try to send the alphabet to spin so they can make their own puzzles)
