The Ruins; Tamoguna
Found in a crate inside Crawl’s tower. There were 4 single beds in the room, and there were 4 known Eladrin in the tower.
The journal is in Elven. You didn’t have time to read it all, but the last few pages detail how Aeveln, the author, looked forward to bringing about Arannis’ plan “inspired by the plans of the first Sorcerer Kings.” It also mentions his love for his home, the Land between the Winds, and how he looks forward to getting back to “grove of masters” near “the Shadow King’s home.”
