Clans

Start a clan from the clan panel, or accept an invite from another player. Founding or joining a clan needs a verified email; a guest account cannot. Clan members count as allies, so swarms sent to their planets reinforce them rather than attack. The clan leader handles invites and can kick members.

Collapsing a galaxy's black hole requires holding every sun in it, and suns held by your clanmates count toward that. A clan takes a galaxy much faster than a solo player, and a contested galaxy is hard to take any other way.

The prestige level a collapse grants goes to every member who holds a sun in that galaxy, and to the member who owned the black hole. A member who holds nothing there gains nothing, so it is worth each member taking a sun of their own rather than letting one of them hold all of them.
