Will Morgan and his friends be able to return to Heat Lake?
After helping the humans accomplish their mission, Chief Derek promised the Striders he will build them a lava tunnel that will cross through Doom Mountain and reach Heat Lake.
The tunnel construction started smoothly and right on track until the builders hit a mysterious block that could not be removed. Worse, it is said to be radioactive as the builders who touched it have fallen ill with a mysterious disease.
Something mysterious emerged from Doom Mountain. Will the Striders be able to return to their home now? Is there a cure for the mysterious disease? Will the Striders fall ill as well?
