|— In-game Outro|
As its name implies, the Lone Fortress is a large, frostbitten castle located near the center of the island. The castle seems to be in a severe state of ruin on the outside and inside, but still managed to survive the cold winds to be used by the local illagers for training and normal lives. Outside the castle, frozen ponds can be seen with some lilypads even stuck on the ice. Within the castle, a small library can be seen as well as various winding paths and even a kitchen and a buffet room filled with Vindicator Chefs. Various doors can be seen blocking the winding hallways, which all lead to a large indoor garden and room and a Grand Chamber where the Wretched Wraith can be fought above a frozen arena which rises from the bottomless pit. Near the exit, a dragon statue can be seen, and two paintings as well within the hallways, depicting the Arch-Illager with the words weak and foe vandalized upon it.
