After completing the [[ 社区中心]] [[收集包]] or the [[Joja社区发展项目]], [[ 玩家 角色]] can trigger a cut scene at the [[ 铁路]], where the Wizard will request they find a 黑暗护身符, which can be found in a chest within the [[ 突变虫穴]]. The 突变虫穴 can be accessed by speaking to [[ 科罗布斯]], who will reveal the entrance in [[ 下水道]]. After obtaining the 黑暗 护身符, bring it back to the 铁路 area and place it on the artifact blocking the cave. Inside the cave is a teleportation rune which leads to the [[ 巫 婆 沼泽]].
