Between the Aspects is a tough subject to cover, mostly because as has been already stated a Mask provides the Eldar with a completely alternate psyche to their true person; ergo they have no bonds other than Aspect, Shrine affiliation and sometimes Craftworld. It may come down to making up your own glyph system, Eldar script always reminded me of Japanese Kanji. Perhaps sentiment markings like 'Loyalty', 'Sacrifice', 'Purity', 'Absolution', 'Dedication', 'Masked' etc. Notions that transcend any 1 aspect and are foundations of the collective paths. Their reasons for adopting the identity of the Mask. You know I'd like to see runescript on armor panels that contain translated phrases with suitably powerful themes that convey the necessity of the Paths: "Freed of Vengeance. In Vengeance clad", "Blade of the Path, Wielded by its Hand", "Liberated from Perfection. Flesh Unbound", "Avatar. Battlemaster. Peacebringer" A little goofy for Eldar but that's why you guys pay fluff people. Anyway, linking this here from someone crazy enough to collect all the known Eldar runes , via Bell of Lost Souls. They may be useless for your purpose but they could probably make a good jumping point, especially the Lettering Runes and Jes Goodwin's designs at the bottom. Always comes back to Jes Edit: Hmm. Just realized I'm here advocating for the Eldar equivalent of a 'Tramp Stamp'. Go me.
