The Shek live to fight for honour and glory. The weakly flatskin live to SERVE the honourable and glorious. You will pay us tribute when we need. Do you finally bend? Or must we give you another show of strength?

Return for Tribute is an event that triggers if you accept paying tribute in the Tribute Round event, or if you have failed to defeat the Return For Blood or Shek Challengers events. It also requires that Bayan, Esata the Stone Golem, Seto, Bugmaster, and the Holy Lord Phoenix to all not be killed or captured. If even one of them has been, the raid will fail to trigger. It will also fail to trigger if the player is allied to the Shek Kingdom.
If all the conditions are met, the Shek Kingdom will trigger an assault on the player's base. This assault will consist of 1 squad, made up of 5-8 Shek Warriors and 0-1 Shek Scouts, led by an additional Shek Warrior.
Once the assault arrives, the leader will give a short speech, based on whether you previously resisted giving tribute. If ignored or refused, the Return for Blood event will trigger in 24-30 hours, assuming you had not previously resisted paying tribute. If you had previously refused, it will instead trigger in 12-24 hours.
If tribute is paid, the assault's forces will wander around the base, looting food from any food storage containers they can find. Eventually they will leave, and another Return for Tribute event will trigger in 100-150 hours. (Note: It is possible to pick up all your food before paying tribute, and the assault's forces will not react to it. Even if they find nothing, they will leave satisfied.)
Like most tax Events, if the campaign is defeated by a third party faction like bandits or wild animals on the way to the player's outpost, it will prevent any future tax visits from the faction until the player's next import. This is due to the long repeat limit timer, and the fact that it doesn't consider being defeated by a third party as the player killing them. This can be exploited by purposefully luring hostiles to the event's forces while they en route to the player's base. Though in the case of the Shek Kingdom here, it is possible to reactivate the tribute events by failing to defeat a Shek Challengers event.
