Twilight is when the Sun lights the world without being present. It's also a Battlefield Enchantment for Glamour Mages.

If a combat round is six seconds long, like in Dungeons & Dragons, then battles always start ten minutes (100 rounds) before Twilight.

Twilight only occurs where the Sun can shine (so not indoors, in Deep Seas, in Caves, or in other Planes), but the 100-round timer is important in all battles. Once Twilight happens, all buffs, debuffs, and battlefield enchantments end. This includes all temporary traits, such as "Blessed" (on those who aren't permanently blessed) and "Gone Berserk". Since scripts are only for the first five actions, whether or not a fellow reapplies their magic is entirely on them; on the other hand, a Berserker cannot go berserk twice in a single battle.

After Round 100, the attacker has five minutes (50 rounds) to finish things up; otherwise, they "turn-rout". A turn-rout affects everyone except for, ironically, the Berserk. In addition, it becomes nighttime, applying a Darkness penalty of -3 to Attack Skill, Defence Skill, and Precision; this is known as Nightfall, which is also a Glamour Battlefield Enchatnment. If the battle started at night for some reason, such as in an Assassination, Daybreak occurs instead and the night Darkness ends.

Once Round 170 is reached, the defenders "give up" and also turn-rout. Once Round 200 is reached, everyone on the battlefield dies of mysterious circumstances, a situation known in Conquest of Elysium as "Starvation".

Twilight can be called early as a Battlefield Enchantment by a 3 mage with 1 (or a 2 mage with 2), but only during the day. It doesn't work if any Darkness effect is active. It also doesn't work in the presence of a Sun, such as Buer - Goat Sun, The Forbidden Light, or a few Pretender "chassis". It also doesn't work if a Second Sun is in the sky, or if the rival Solar Brilliance Enchantment is in play.

This Twilight does not have the same magic-ending effects as hitting the Round-100 timer.

Twilight itself applies a -2 Precision penalty to everyone on the battlefield. It also provides a +1 pathboost to all Glamour mages in the battle. The Precision penalty is affected by Darkvision and Spirit Sight, and outright negated by Blindness (the Affliction or the Trait) and True Sight.
