What does the Crimson Mantle’s aging block do?

[Peelee]

He is however an expert on how Redcloak actually functions having known him his entire life and all.

People mature and change because the passing of time forces them to. Right-Eye gave up on the plan because he wanted a family and realized he couldn’t do both. Redcloak being eternally young looses all reminders that his body would give him of the limited time he has. He won’t change until forced to by something he cannot ignore, like the ending of SoD.

Redcloak doesn’t want to change, very few people do as changing is hard and often painful but unlike real people and (most OOTS people) he can (mostly) afford not to.

Except all the other times Redcloak changed.
