New crackpot theory: Redcloak sacrifices his life to defeat The Snarl by throwing the Crimson Mantle into the rift, thus sealing it with purple quiddity and instantly aging himself to the point where he dies of old age.
I haven't thought in terms of sealing the rift, but I've definitely thought about an ending where Redcloak realizes his life's work is for nothing, so he just takes off the Mantle and lets himself die.
