Doctor Orbon is located in the East Ardougne chapel, and is involved in the Sheep Herder Quest. He sells the Plague gear that protects players from the poisonous sheep. He seems to be a scientist who has invented a suit that helps protect people from the infected Sheep around the north of East Ardougne. The quest cannot be completed without his help.
If talked to while wearing full mourner clothes, he will ask for his payment, saying 'he won't keep the charade any longer for free', and asks to tell the head mourner about it. This implies that he is part of the Mourners.
He is one of the NPC's you can start the Ardougne Diary by talking to, and will give you the Ardougne cloak 1 as a reward for completing the easy tasks. If you lose the cloak, you can talk to him for another.
