Finally... a conflict arose recently.

A small clan appeared and settled in a space within our allied territory, then attacked my alliance's gathering units without any warning. When the alliance leader spoke with them, they claimed they attacked because we were encroaching on their land to gather resources... Honestly, ??? I can't understand why they would act so unreasonably towards the current World #2 alliance, but perhaps it's their way of showing consideration so we don't get too bored. Finally, a war broke out, and we had our first small-scale PvP engagement outside of events. The next season is coming soon, and we'll be merging with other worlds, which is when this will likely become the norm.
