Penda is a citizen in Burthorpe, a bar patron and hangs out more at the Toad and Chicken than his own house. When talked to, he may randomly say, "Ich bin ein Badger", even in English servers.
Treasure trails clue scroll[]
For the clue scroll: Go to the village being attacked by trolls, and search the drawers in one of the houses.
Go to Dunstan's house in Burthorpe and search the drawers: "Wait till I get my hands on Penda, he's nicked the key again."
Go to the bar (the Toad and Chicken) and kill him to get the key.
Go back to Dunstan's house and open the drawer with the key in inventory. The key disappears and you will obtain another clue scroll or a reward.
