Midnight Mansion

The Midnight Mansion was the home of the Midnight family back in the early days of Reefside, including the days of the original Nitro Rangers.

Geauga Society Annual #1
However, the heir, Romulis Midnight, died fighting in World War I, with the lord, Augustus Midnight, a short time later. Then the daughter, Pollyanna "Polly" Midnight disappeared. Then the mother, Kosarin's aunt Emma, died of Spanish Influenza. Every since, no was wanted to take the mansion for any price, believing it was cursed by the Stradun.

This would true as Kosarin had captured Polly and Anton stole a portion of her youth to create Jezella.

Lost in the Midnight Mansion
Over a century later, Polly had turned into an obscurial force, chained deep within Vladsmir's world that finally broke when Kosarin unleashed the Dungeon Beast on Reefside. This finally gave Polly the chance to escape and learn that the obscurial force unlocked a sort of magic within her that knocked out the Morphing Grid.

Without their ranger powers, Laser returned to give them new powers to defeat Polly. However, she crashed into the house of her childhood in its decript glory. Her obscurial force, which had protected her earlier, nearly blew her apart. Instead, the power reversed the effects of time on her childhood home and regained her memories, discovering an old drawing of her brother's, Seven warriors that would protect the family fortune.

Her work did not go unnoticed and it sprung a psychological trap on the Coaster Force: In order for them to live, they would have to defeat the warriors that protected the Midnight Mansion.

Due to being creatures created by a child, Peter was able to imagine new powers for him and his team to use that destroyed the mansion and Polly Nomial for good.
