A Chalderan expedition came to Earth in 1883 to mine Krakatoa, angering the natives, who saw them as defiling the mountain. The Tenth Doctor and Rose Tyler discovered the Chalderans' base and were captured by them, being placed upside down for an undetermined period of time as a form of torture for trespassing. After tricking the aliens into arguing amongst themselves, the Doctor and Rose escaped. The pursuing Chalderans were killed after running into a waterfall. The rest perished in the island's explosion. (COMIC: Under the Volcano)
