Reaching Ainsel River Main
Ainsel River Main is located in the upper section of the Ainsel River Region. Unfortunately, the lower section of Ainsel River doesn’t give a path for you to access the upper section.
To explore the lower section, you have the Ainsel River Well in Liurnia of the Lakes to get there. However, you’ll need to choose between one of two paths to explore the upper section.
Through a Waygate in Renna’s Rise
Renna’s Rise is located in the Three Sisters subregion of Liurnia of the Lakes, specifically west of Caria Manor. To gain access to the subregion, you’ll have to defeat Royal Knight Loretta’s spectre.
The entrance to Renna’s Rise is blocked by a magical barrier. You can only unlock it by obtaining the Cursemark of Death, which is located at the top of the Divine Tower of Liurnia.
Once you unlock Renna’s Rise, go to the topmost room and examine the Waygate to reach Ainsel River Main.
