Steadtree

The steadtree is a species of tree native to the equatorial rain forest on Yih. It is this tree that the yinrih evolved to dwell in.

Fruit

Steadtree fruit co-evolved alongside the yinrih's nonsapient ancestors in order to use the yinrih as seed dispersers. It's about the size of an apple, and Its flavor is uniquely adapted to the yinrih's poor sense of taste. It is mildly sweet but has a very, very strong sour flavor. Humans liken it to Warhead candies. The skin is deep bluish purple with a vivid violet sheen, and it's flesh is an extremely saturated shade of blue.

The fruit plays an important part in the Bright Way. While it isn't used in the liturgy itself, it is distributed afterward to visitors, irrespective of creed, in a manner similar to Antidoron.

Other Parts

Other parts of the steadtree are used in various rites. In particular, the large, broad leaves are used for recording scripture. One of a cleric's duties during her formation is to copy scriptural passages onto steadtree leaves using her own ink. These leaves were the object of the yinrih's scent marking behavior, and thus ultimately their first writing medium.

Young branches are distributed to the faithful during the liturgy celebrating the kindling of the Fire of Understanding. They're supposed to serve as a reminder of the yinrih's origins, but they're as often as not wielded by pups as instruments of annoyance against their litter mates.
