Currently, there is no widely documented or official "full guide" for a title specifically named Villainess Quest -Kalgos- Temptation of the Red

If you are engaging with this as an interactive "Quest" thread, you can expect:

You are Lady Elara Kalgos. In the original timeline of the "Shattered Ruby" chronicles, you were the arrogant antagonist who died at the hands of the Hero after trying to seize the Imperial Throne. Now, having regained memories of your "past life," you find yourself standing in the Great Hall of the Blood-Glass Palace.

If this title refers to a specific community-led "Quest" (a story where readers vote on the protagonist's actions), a blog post should capture the high stakes and the "Red" thematic elements.
