Reach Scholastone

After receiving Alustin’s letter, get the required garb from the black market fence in Hernand. Travel toward Scholastone through Witchwoods and use the route to learn Focused Force Palm if the opportunity appears.

Gate to the Otherworld

At Scholastone, help Octavius activate the experimental gate. The situation goes wrong when the rift opens and Tenebrum appears, forcing Kliff to deal with the consequences of forbidden research.

Spire of the Stars

After the energy beam appears, use the Dean’s key to enter the Spire of the Stars. Solve the ascent puzzles, enter the Sanctorum of Insight, and expect the chapter to end with more questions than answers.
