Dark Watchguard Kimberly

Lore
Kimberly, sword in hand, stood alone before the rusted gate. Only by defeating her was one allowed passing into the bleak courtyard beyond, but in normal circumstances, few felt the need to challenge her. She defended a crumbling castle where ghouls writhed and shrieked in the darkness, and there was not a single object within that humans would ever desire.
