Chasm of the Abyss illusory wall

Overview

Location

At a fork on the first descending path, near the Humanity Phantoms: take the left branch, fall through a disappearing floor, then follow an illusion that appears to be Alvina -- the actual illusory wall is behind the third such illusion encountered.

Leads to

A shortcut elevator back to Royal Wood.

Note

Corrected: the reveal mechanism recorded here previously read like a normal attack/roll/Seek-Guidance wall (the default assumption for this dataset), but per the primary source this wall is uniquely gated behind a multi-step sequence (disappearing floor, then following a false Alvina illusion) rather than a simple physical reveal. leads_to (shortcut elevator back to Royal Wood) was independently confirmed correct and is unchanged.
