Hakku used to have mate named Kilaki. When their makes were being decommissioned, they planned to run away together as Rogues. When they arrived to the decommissioning station, they escaped running to the catacombs underground the Horizon city. Though, while they were running they were being chased by a pack of Hellhounds sent by the humans (basically dog-like beasts that have the venom of komodo dragons and super SUPER sharp claws with spikes on their back...yeah they're super scary). Through Hakku's struggle to break her mandates, Kilaki did all he could to protect her. He stopped and turned around and immediately was mauled by the pack whispering 'Run' to Hakku while they were distracted. Hakku ran as fast as she possibly could to the catacombs but shortly was chased by a lone Hellhound. At the entrance, the fought long and hard and finally scratched deeply into Hakku's left side from her spine to her bellybutton where she finally yelped and pushed the hellhound killing it. She finally escaped to the catacombs taking a few short breaths bleeding excessively, she sits down for a few moments in utter pain and decides to dig out the microchip that was buried under her barcode on her right shoulder (which has been tracking her ever since she was born). Shortly after, the rest of the pack tracked her scent to her and she ran deep into the catacombs being pursued for several miles until she finally starts to hallucinate and lose balance due to the lack of energy and blood. A rogue chimera named Bennkay finally swoops in to her rescue killing and driving off the hellhounds as she slowly passes out. Bennkay carries her to the base and tends to her wounds by wrapping bandages and watches over her for days until she wakes up and finds Kilaki didn't make it. To this day, she is still devastated by his passing.
