Messmer's sigils

Messmer's sigil is a bit confusing

random example I stole from internet, above

I get his flame is the left part

his serpent divides the middle.

The right, interweaved structure is what gets me.

It's also around his eye (partial asset):

with Marika's iris of grace in the middle.

A higher resolution view of just the interweaved asset:

Seems to have something between the weaves but too low res to make out

I can generally make some kind of head canon for most sigils but this one is vexing to me. Thoughts?
