The youngest triplet of the Nivek family, she took the longest amount of time to born and unfortunately, her head was stuck in her mothers birth canal for too long and an emergency VBAC was used. Her mother died as a result of her injuries, but Kaatje survived with minor trauma. Upholding the status of the Nivek family, the triplets proved to be as legendary as their past relatives. Kaatje is often quiet, her presence being intense enough for the 3 of them. Other times, she enjoys instigating fights and antagonizing others and watching them crumble to the brutality of her siblings. After being handpicked by Killer Koiwalski, the three of them headed to Jeleni Ostroc to join with the squad for a raiding party. Squatting the entire boat trip, getting to the island was rather hectic but proved to be effortless for the triplets.
