Holdarans are bio-mechanical constructs that are fully sentient, but have always lived inside Holdara and hence have no idea that they are unusual in any way.

Immutable Features
Holdaran NFTs are each unique with many randomised elements:
...
The Holdaran’s NFT image is their “graduation photo” (PFP) that never changes. Note that it doesn’t mean the character necessarily starts the game with the outfits or weapons – those items are just what they had at the time of the photo, though they will likely relate to their generated background biography.
Mutable Features
All other aspects of the characters Holdarans are mutable either via customisation or gameplay:
...
All these mutable aspects are reversable so that any future purchaser of the character can effectively reset any modifications they don’t like.
In-Game Customisation
Everything in Holdara must be earned or bought – you don’t simply go to a menu and choose a different outfit or colour scheme from some presets. Even outfits/equipment you own can only be swapped out when you have access to the inventory they are stored in, so for example changing clothes requires a character to be carrying the outfit, or to return to where it is stored.
