The requirements for what constitutes a juvid are defined by Pashaist holy law. Most notably, juvids are required to have a tall tower-like structure (or minaret) from which the call to worship can be recited; traditionally, these towers had to be the tallest building in the vicinity. Juvids must also have a large, open courtyard where Pashaists can congregate to worship Hosha. Juvids (and most distinctively minarets) are built in a variety of different architectural styles, associated with different areas and time periods.
Aside from their religious use, juvids are commonly used as social and educational buildings, and they often serve an important role in Pashaist communities. During the secularisation of the Helsonian Union, many juvids were repurposed as hospitals, schools, museums or administrative buildings.
Worship in juvids is led by a Pashaist preacher, known as an ernujas.
