( AUDIO : " Death and the Daleks " , PROSE : " . . . Be Forgot " ) Hass was a famous gardener , an unusual profession for a Martian , although he took his work extremely seriously . At first , he found it difficult to change the gardens in any way due to a mutated Damon ' s Tender plant which had absorbed the personality of Mr Crofton and kept undoing Hass ' work . Eventually , he and Bernice Summerfield found the plant and removed it , allowing Hass to make his mark on the Collection .

On Braxiatel ' s advice , she sent Hass and Joseph , as the environmental conditions of the Mimsphere would be hazardous to anyone else on the Collection . ( AUDIO : " The Judas Gift " ) Braxiatel ' s reasons for suggesting this change became apparent when Hass brought the war to an early closure by releasing months worth of stored radiation from his pressure suit , instantly destroying everyone on the Mimsphere .
