Elena

Elena is a NPC who is heavily involved in both the Plague City and Biohazard quests. Elena is the start for the Biohazard quest. In the former, players save her from her entrapment by the Mourners in West Ardougne. In the latter, players are to aid her delivery of three different chemicals to a scientist in south-east Varrock. She is also somewhat involved in the quest Mourning's Ends Part I when the players need to visit her in order to get a sieve. She is scared if a player visits her disguised as a mourner. After Plague City, players can find Elena in her house in north-west of East Ardougne.

Elena is the daughter of Edmond and Alrena, who live together in a house just west of Elena's house. She is a missionary who voluntarily went to the plague-infected West Ardougne to try to help the people there.
