I can't complete this quest: is not in my city or in the others

Guys... i went visit the empire of another player. There i found 2 quests. I completed them with success, but now how can i achieve the prizes and the exp? i don't remember the name of the guy i visit, so i can't return in that empire to talk with the quest givers
|||Your referring to mamu peepaws and ol man Fischers quest I believe. Im pretty sure you can turn this quest in at anyones quest building who has them. I have both, you can visit me and try that if you like. In the chat window type: /visit Prawnasaurus. Then have a look and see if you can turn them in there.
|||thanx, it is the ol' man quest
