Technically no, BUT the gelfling characters imply that their parents died when they were young. In a flashback, one characters mother hides them away and the mother is snatched up by a monster
Various creatures are shown in small cages and are presumably used for experiments or rituals of some type. Some small creatures are served as a live meal.
Both Jen's and Kira's birth parents are dead as all of the other gelfling died before the start of the film. Jen's mentor also dies of an unspecified illness near the beginning.
When Fizzgig jumps out of a hole barking/growling and scares Jen. It always makes me jump even though I've seen this film countless times. It's very minor but I thought i would mention.
No mutilation occurs, however one of the characters has a single eye that she regularly removes and looks through remotely. Similar to the Fates in Disney's Hercules. May be triggering for some.
Characters get their essence drained from their bodies and it flows through a series of tubes before ending in a vial. It's unclear how the essence got into the tubes in the first place, but it's sort of implied that there are some type of needles going from the victim to the tubes
Technically no, but there is a scene where two characters share their memories with each other in a dream-like fashion and one character is confused and unfamiliar with what's going on
Torture is not strictly shown, but certain aspects might be triggering for some. A few characters are shown being restrained using chairs with metal clamps and are forced to look into a light that drains them of their "essence".
