Tentatively attempting to plot with my muses here, but nothing's set in stone.

Vilari will be infiltrating as a Hecatite-Elf hybrid, the Oracle of Reflections. She lost her powers as a Champion quite early because there's only so much hope a half-breed can be trusted with when both races are more keen on supporting their 'relatable' Champions. Her former powers included being able to manipulate reflections on any surface to create illusions, draw forth duplicates of weapons and other objects, and to converse through reflections with others. Now she can still maintain some illusions and speak through reflective surfaces, but she rarely leaves her personal domain in Questing Country. She serves as the 'wise hermit' whom fledgling Champions sometimes visit to seek guidance or advice. She can be coaxed into leaving her 'home' when a Champion is inspiring enough, but it takes a good deal of convincing to do it.

As for Dick and Ezio... tba;
