This started off as a basic conceptual sketch for the redesign of the Theian valketh - inhabitants of the continent Theia which was devastated by a (relatively) recent war. It is now effectively a wasteland, with the majority of the arid lands having now become informally referred to as the glass sands.
Theian valketh are recluses by nature, especially after the war in which their land was devastated. When seen, they are often said to be covered full-body in cloth-like material. Foreigners are unsure what the purpose of this is. Some assume the Theians are terribly deformed by the radiation plaguing their home, and they hide themselves from prying eyes; others think it is simple environment-appropriate wear in the arid wastelands; few consider it to even be religious in nature. The lattermost theory is not unfounded, as the neighbouring continent of Arthiria, renowned for its acceptance of spiritual leanings, is more than likely to have an influence on Theian culture, especially in their war-torn recovery period.
To leave exposition mode, the last point is actually true. Certain parts of Theia have adopted spiritual beliefs in a sense, and this individual is one of many adults which journey to Schiehallion, a supposed crystalline mountain which is hollow, to undertake a rite of passage of sorts that was laid out in pre-war times by the modern Theians' ancestors. What this rite entails is unknown - only the individuals which embark on this pilgrimage ever know. A Theian may travel alone on this task, or if so desired, take a mentor figure with them - but either way, the 'new' one to the rite must enter Schiehallion alone.
This character in particular is one I've had swimming around in my head for the last couple of days. I've got his name down as Eilean ("ay-lin"), and I think one of these days it'd be intriguing to write about his pilgrimage in particular. It'd be an interesting insight into a rather unique area of Lorranth otherwise neglected by the rest of the Four Nations. Short story format, likely - but it's something for me to consider at least.
(As one would assume, the revamped Theians are heavily inspired by the PS3 game Journey, which I played only recently, but has impacted me emotionally on an unprecedented level. Other inspirations for this and other Theian aspects [not yet publicly introduced] include Firefly, Spec Ops: the Line and Final Fantasy.)
