> Four friends of an ancient spellcaster, each one with their own symbol
> One of the symbols is associated with someone with the same last name as Rudo's
> The same symbol that's on the Watchman series (Rudo's gloves, Zodyl's coat, Amo's boots, Tamsy's book, Gountess's pendant)
> The same symbol resembles the "face" of the titan in the sky between the Sphere and the surface

Will the other symbols become important later? Do they have their own series of objects or titans associated with them?
