After hours and hours of work, tierael and I managed to figure out every last aspect of the cloak on his character.

I will leave the description of the cloak up to here and will post this here for everyone to just enjoy the design.
In the end this was a joint effort by the both of us. His ideas, some refining by myself and we fueled each other on.
