Who is its author anyway? :confused:

We need to think about how to proceed. Either an additional passage, or perhaps tents for the opposing players.

You could place the opponent's tents somewhere in the swamp at the very end. Then whoever is the strongest goes across the bridge. And whoever likes to run and swim heads back to the boat.

How should I put it. It's terribly inconvenient to get out of the secondary area.

A teleport from the small neutrals seems simpler, I think. Then nothing needs to be changed. The second castle is still taken in no time. And there's no need to go there a second time with an army. Right?

And to prevent ruling from the sea — a Seaman's Hut for each player in the underground near the swamp, under guard.

Can't argue with that.

Since the party's already started, I offer my services for subsequent editing.

All the more so here.
