I used to play Lords Mobile a while back (I plan on going back soon) and we used to have a thing called kingdom wars where players from two or three kingdoms went head to head to see who is superior. I once ported to a hive (a cluster of players in a specific area was called a hive) and I saw this one player and attacked him. Unknown to me at the time, he was attacking a guild from his own kingdom(which is stupid for obvious reasons). So I destroyed him and I started getting messages from the members of that guild that I was their savior etc. Long story short - that guild ended up helping us to win the kingdom wars and shortly after the event they migrated to our kingdom where our guild (we were the rulers of the kingdom at the time) took them in as allies and protected them.
