Skirmish: Goblins
I wish to go to skirmish goblins “As a Weekly Communal Action”. If nobody joins me moments before this action is due/becomes permanent/is executed, this action is immediately vetoed, having no effect, because I do not wish to lose gold, and the ruleset says “If this number is two or greater, the Knights Win the Skirmish. Otherwise, the Knights Lose the Skirmish.” Meaning I cannot win by going alone. That is the reason why this action will be vetoed and ineffective if nobody joins me moments before it takes effect/is executed, so I won’t lose money! :D
Smart, eh?

The Skirmish rule requires its initiator to select “a random Monster Group”, not to pick one. (Interesting that this doesn’t actually default to requiring a GNDT roll.)
Nobody has to join you for a Skirmish to succeed or fail, it just happens. In this case it would have succeeded.
But since it’s not clear you picked a monster at random here, this looks like an illegal Skirmish.
