When West Ardougne was quarantined, Elena snuck into the city to help, intending to only be gone a few days.[1] Alrena provided her with a gas mask prepared using dwellberries, intended to help repel the virus.[2] However, three weeks passed with no word from Elena,[1] and Edmond planned to sneak into the city himself to find her.[3] A passing adventurer offered to go in his place, and Alrena prepared some spare gas masks for them, hiding them in case the mourners came by.[4] She later got word to the adventurer that the mourners were becoming suspicious[5] and helped them with locating ingredients for a hangover cure.
She seems to have some skill with medicine, being knowledgeable of the medical benefits of dwellberries and keeping a pestle and mortar nearby.
