Isabela is originally from Rivain, but has traveled far and visited many places during her life. She was once married to the original owner of The Siren's Call, until he was killed by Zevran for unknown reasons, leading her to inherit the ship. She doesn't seem too regretful over her husband's death, calling him a "greasy bastard", explaining her rather cordial relationship with Zevran. She has picked up a special fighting technique during her travels, one that depends on speed instead of strength. Since she has learned this technique by dueling many different warriors, she calls herself a "duelist".
