Sponsorship the way you would do it
In the Legend of Zelda series of video games, Hylian means from or related to the mythical land of Hyrule. The term generally refers to the Hylian race, a race of humans with certain magical abilities. They have pointed pixie like ears. Most hylian in hyrule live in the Hyrule Castle town, though a few individuals inhabit land outside of this town, namely Talon of the Lonlon ranch and the Lakeside Scientist. The Hylians are closely related to the Sheikhah, Hylians who live in the village of Kakariko at the base of death mountain.

The hylian written language is based on rectangular runes, and is in part derived from japanese hiragana, katakana and romaji. The script is syllabic or more precicely moraic, and each symbol represents either a vowel, consonant - vowel combination or a sylable final n.
