A season-long fight for control of buildings on your state map, with weekly battles.
TL;DR Pick battle times your alliance can actually attend, rally to take buildings, keep reinforcing after capture, and watch both the 30-minute and 2-hour timers.

🗓️Season & registration
Seasons last 8 weeks, with a registration stage and a battle stage each week.
The map has 12 Fortresses and 4 Strongholds. In a new state’s first season, Strongholds usually appear around week 4.
Only R4/R5 can register. Buildings you captured carry over automatically and can’t be changed. Each week you can add new targets — the official help says one new building; guides say one Fortress plus one Stronghold.
An alliance can end a season holding up to 8 Fortresses and 4 Strongholds. At season end, everything resets to the NPC defenders.
Building counts and the Friday battle day come from community guides. The registration and occupation rules match the official help center.
⏱️Battle rules
Leaders choose 3 preferred times from 5 options. The server sets the final time based on everyone contesting that building.
Hold a building for more than 30 continuous minutes to occupy it. If your garrison is removed, the timer resets for the new holder. If nobody manages 30 minutes, whoever holds it when the 2-hour window ends takes it.
You can rally a building or attack it alone. Leaving your alliance during the battle phase blocks you from another alliance’s fortress battle that week.
🎁Rewards
Fortresses grant better rewards than Strongholds (official help center). Tap a building, then View, to see its current rewards.
First occupation (beating the Phaethon Mercenaries) pays participation rewards, alliance rewards, and allocatable rewards that R4/R5 hand out with a per-person cap. Control rewards go by mail to members holding the building when the battle ends.
Fortress rewards can include gems, speedups, resource packs, Gold and Platinum Keys, Hero XP and hero fragments.
🎯Strategy
Choose battle times with your strongest attendance, not the earliest slot.
Assign roles: coordinator, rally leaders, garrison leader, reinforcers and a reserve team.
Use rallies for the first capture, then keep reinforcements flowing. The garrison bleeds every time it’s hit.
Track the 30-minute occupation timer and the 2-hour battle timer together.
Defend only what you can hold, and agree on a reward-sharing policy before the season starts.
