Adeline can handle fighting and could, in a pinch, take care of technical duties (thought it'd be fifty/fifty at best because "WHY IS EVERYTHING SO BACKWARDS? CAN'T YOU JUST USE SENSIBLE THAUTERMAGICAL TECH LIKE EVERYONE ELSE?"). She's also physically tough and with the monk training and various dragony traits attached to her, she'd be a good tank.
If no one is interested in having her help/getting dragged along by her because bored and ADVENTURE!, she'll probably get involved in keeping the peace in the city/fighting Eas' monsters.
