Reventine birthday

A traditional Reventine brirthday celebration involves not only celebrating a person's anniversary of birth, but is also one of the last callbacks to the Reventines' ancestral nomadic culture before settlement.
At the eve before the birthday, the wife, mother, or any other closest female family member prepares a traditional steppe drink from milk, honey and crushed enhse buds, a herb with hallucinogenic properties abundant in the Revesteppe, called temelh. The prepared jug of temelh is then covered with cloth and left to mature overnight to let the enhse properly bind with the milk and honey and in the morning the drink should be ready for consumption, a slightly greenish milky substance with mild psychedelic effects on the drinker.
Preparations for the celebration start at dawn with a an old poem recited to the rising sun, serving to let the sun know of the holiday and ask for its blessing for the celebrant. If the dawn happens to be rainy or overcast, a different poem is recited, asking for the blessing of rain, instead. As far as weather goes, only hail or a violent storm are considered to be bad omens, both of which can, however, be corrected through a ritual called step-covering, where the celebrant covers the steps in their house with flour to see if a demon is walking through it, whilst the rest of the people at the celebration sing a traditional song asking the elements to bless the person's birthday. This is why even Reventine houses without multiple stories or a cellar have at least a singular step for this specific purpose. The ritual is believed to ward off bad luck whether the weather calms or not.
After the morning weather rituals, the celebrant has to leave their house until noon, dressed in their best clothes traditionally to go on a horse ride across the steppe, but in modern times, they can do what they want except for drinking alcohol. While the celebrant is away, the family and friends prepare food, decorate the house and draw symbols on the door in order to keep the purified house from being taken by a demon for another year.
Upon the celebrant's return at noon, they are seated in the middle of a circle of friends and relatives, who sing another traditional song and have to drink from the temelh, inducing a strange state of mild hallucinations among the singing, traditionally considered a small peek into the spirit world. After this ritual the lunch is served and the celebration starts in earnest, dancing, drinking and eating well into the night, even though traditionally the celebration was to end upon sunset and no alcohol was to be drunk. The celebrant and their partner have to drink the rest of the temelh before going to sleep. If the celebrant has no partner, they have to drink half and pour the other half in a half circle in front of the door, which is supposed to ask the spirits to deliver a partner to the celebrant by their next birthday.
The guests stay at the host's house for the night and disperse in the early morning, returning to their lives, with the host being left with the task to clean up the mess after the celebration and is also required to do extensive housecleaning, as a sign of a rebirth. Birthdays are very important for the Reventines and by imperial decree, every lord has to respect their subject's right to celebrate them, being required to give them the two days off work unless there is a war or other crisis in place.
