Being and Non-Being (Ser No Ser) is the Angel of Life and Obliteration, a pleromatic entity that embraces both Ariadna and Ärsvan at culminating moments. It offers orbs of eternity and obliteration and embodies the duality of life and death, creation and destruction.
It mediates in Ariadna’s redemption and Ärsvan’s sacrifice before the Cathedral of Paris, at the end of the Templar gesta (campaign-cycle). It also appears in the cosmological poem Pleroma.
