Silverstars generally operated in either big cities by the coast that relied on the sea for food and trade, or on the edges of civilization, where lycanthropes were often found. However, they would not stay in one place for a great length of time, instead being grabbed a new cause or mission or simple wanderlust, and would soon move on.
They were an elite group within the church of Selûne. Silverstars were devoted advocates of freedom and tolerance and were dedicated seekers of truth. They were considered to be close to the goddess.
They were thought to be "touched" with prophecy and they occasionally received visions from their goddess. They commanded lunar energy and some of the power of the moon in order to serve Selûne's aims on Toril.
In the hands of a silverstar, a magical or even mundane Moon's Hand mace was more accurate and more damaging, and harm creatures that could only be hurt by enchanted weapons. Later on some silverstars learned to treat any heavy mace they wielded as a Moon's Hand, transforming it into an enchanted weapon with shock and later shocking burst powers.
Many years before the Era of Upheaval, during the time of ancient Netheril, could cast spells such as protection from evil, locate object, locate creature, abjure, find the path, dream, holy word, and restoration or regenerate.
Circa the mid–14th century DR, Silverstars could cast certain bonus spells, namely starshine, moonbeam or lower/raise water, moonblade, moon path or true seeing, the latter of which was known as "prophet's sight". After 1372 DR they could freely cast moon domain spells, and finally received the moonfire spell.
Veteran silverstars could launch shooting stars from a hand or their eyes, up to three per tenday, to a distance of 70 ft (21 m). These glowing projectiles with tails of fire exploded on impact or at the end of their range and caused much damage over 5 ft (1.5 m). After 1372 DR, they could only project small orbs of glowing lunar energy from their eyes. Referred to as the tears of Selûne, these motes were were similar to dancing lights.
Also around that same time, senior silverstars learned to resist Shadow Weave magic with a power called "moonshield", becoming resistance to enchantments, illusions, and necromancy and against spells of darkness, whatever the source of the magic.
A silverstar was not immune to lycanthropy, and could make some use of the matter if infected. If the infecting lycanthrope was morally upstanding, without any care for ethical standing, or the moral and ethical outlook of that creature was in line with that of the silverstar, the priest or priestess of Selûne became a natural lycanthrope. In those cases, the silverstar could control their transformations, and thanks to the blessing of Selûne, were not vulnerable to silver weaponry. Any transformed being that turned to evil could not remain a silverstar.
Over time, any lycanthropic change underwent by a silverstar caused them to become a natural lycanthrope, and remain true to the person they were. Their memory remained intact whether in their humanoid or lycanthropic form.
A being of any race could become a silverstar, but they were required to be reasonably wise and hardy In the time of Netheril, they could be any good alignment, but in the 14th century DR they were required specifically to be chaotic good.
They needed to be capable in battle, especially in the dark or when unable to see, and to master a combat style based around dodging and making mobile attacks. They should be skilled in finding their way and in scrutinizing the motives of others. They also needed the ability for divine magic; clerics needed access to the Moon domain. Most began as clerics, others as rangers.
