"Poeta used to be a place Daeva visited to complete their Ascension." As thanks for helping the legion, Nania told you how you might recover your strength. Once known as the island of poetry and song, Poeta was a beautiful land where Daeva and the Spirit Elim coexisted. Many Daeva seeking to ascend would head for Clione Lake, with its abundant Odyle energy. Daminu, the leader of the Elim, played a key role in aiding Daeva with their ascension. Guided by the scouts' reports, you arrived at the Clione Lake and came upon Daminu, the sole surviving Elim.
