Although Sinmara can't fly, but she is an excellent swimmer. While admiral Hornblower maintains the sea defenses, she stealthily completes the missions underwater using her webbed fans, horns and appendages as a sonar. Thanks to training, the lung mutation, she's own magic and Arcane runes Sinmara is works well with breathing. She's invisible in water. Unlike other Sandsurge dragons, she doesn't like sand - she prefers to swim for real.

She is also good friends and co-workers with Nokama - they have a lot in common. Nokama often covers her during combat operations.
