She is infamous in her party for her distinct lack of elven/thiefly grace. She knocked herself out trying to scale a wall once (she kept slipping). This happened on numerous occasions. On one caper, she was disguised in a formal gown when she had to escape by sewer. Taking the greatest care to cling to the ladder down, she nevertheless slipped (botched!) into sewage six feet deep.
Ráwen is just over five feet tall.
