Evernight Isle

Evernight Isle takes commanders to Sakura Isle, a Japanese-themed island plunged into endless darkness by the Nightfall Device. Everything this season revolves around one mechanic: light versus darkness.

The Lighthouse - your lifeline

Your Lighthouse, powered by four zombie-powered Generators and electricians, pushes back the night - it grants Virus Resistance and removes the debuffs that otherwise weaken you constantly in the dark. It plays a similar role to Season 2's Furnace, but with far harsher consequences for falling behind on it - there's no coasting through this one.

• Electricians light your marches, power allies, and activate special structures like the Maneki-neko and the Divine Tree.
• Assign clear Generator/electrician duties within your alliance early - don't leave it to whoever happens to notice it's running low.

Season structure

Season 4 opens with a quiet two-week pre-season of previews and light tasks before the real gameplay starts - use this window to get familiar with the systems rather than rushing ahead. Once the season proper begins:

• Blood Night Descends hits three times a day (roughly 02:30, 10:30, and 18:30), each time making zombies and Doom Elites stronger in the dark - a recurring event every alliance needs an actual response plan for, not just a reaction each time.
• Tactics Cards unlock on Day 2 - a collectible system with two categories: Core Cards (kept permanently at season end) and regular cards (which convert to Profession EXP when the season closes). Building an intentional loadout meaningfully outperforms a random one, even at the same card rarity.

Factions and the Copper War

Unlike the multi-warzone structure of earlier seasons, this is a single-warzone, faction-based season: everyone splits into one of two factions, Kage no Sato or Koubutai, around Week 3. From Week 4 through Week 7, the Copper Wars are fought Wednesday and Saturday over each faction's Alliance Centers - Copper is the season's ranking resource, so your Copper rank directly sets your final reward tier.

The season culminates in Week 7 with a faction Capitol battle and War's Eve.

Resources and what carries forward

Seasonal resources include Stone, Quartz, Magatama, and Copper. Progress this season also feeds into the Armament Institute's path toward T11 troops, which unlock in the following off-season - worth investing in even if the payoff arrives later.
