I can say, it’s not impossible. I did it on the first day of the new event. Everyone at the fotd were nice and everyone got equal shares upon sailing in.
When I read “lost everything”. What did you lose before an alliance was made? If your main focus is the event, you shouldn’t have any loot and wait at the fotd with all lights already made.
Alliance is mainly friends yet to be made. Might also look into server alliances or idk looking for group posts.
(I also hear Xbox lobbies are easier than pc)
