A pseudo-PvP event against NPC 'Arctic Barbarian's Castle' that appears randomly on the map. Combat can be solo OR rally, but you can only defeat castles yourself 10 times per day (losses don't reduce the count) - so castle selection matters. Losses become WOUNDED troops (main city -> hospital, siege -> trap factory), NOT dead; no deserters/souls, so no Horns of Recalling or Soul Crystals needed. The event is wound-adjusted (far fewer wounded than normal PvP - a barbarian side losing ~1M may only wound tens of thousands of yours) and is net resource-POSITIVE (Lv4 ~5-8M per resource type per kill, Lv5 ~8-12M), effectively a resource-earning event; Lv6 is only profitable at Keep 45+. Score mainly comes from OCCUPYING a defeated castle for a period (defeating alone gives little). Three reward tracks: personal-score-achievement (non-competitive - guaranteed if you grind), personal-score rank, and alliance rank. Reaching 500M personal score = 189,000 Gems. Tips: get alliance members to help, have friends take the weaker castles, 'Don't rally' (solo is more efficient here), and if you only need 500M you can just defeat Lv5 (836M+) castles without occupying. Event usually lasts ~11 days.
