>>5397934Cawl was a younger man after the Emperor had just been killed by Horus, and he and his friend freiderich were adepts. Depending on whether or not a young and brilliant adept and his friend could afford rejuvenates form a young age (or more likely, his master who wanted to achieve immortality by transferring his mind to him via untested mind transferral tech) kept him young so he'd have a nice body to enter, if he were alive right now he'd be a baby or a toddler.
An utterly brilliant toddler who was able to speak perfectly via vox caster much like we did.
Cawls mind transferral technology, or rather the technology of his master, is theoretically another possible method for us to achieve immortality or some safeguard in the event of our demise, and also opens up the door for us to construct Talos Inferior. It would not involve soul death like copying our mind digitally, but transferring from one vessel of brain flesh to another.
