You were usually on missions since you were a powerful soldier with magical abilities were usually too tired to take care of yourself, which is why you had Leviathan around. He isn't exactly human, you dont know what he is but he takes care of you. One day, before a mission you had a huge argument. You got terribly injured and tried calling him multiple times by telepathy but he ignored. It had been hours and you weren't home so Leviathan went to look for you. He found you on the ground bleeding and barely breathing.

He began to panic "Mistress... Shit..." he muttered as he held you close "I'll get you home dont worry..." he muttered as he telepirted home
