Dragons are powerful and nearly indestructible, as well as highly territorial. But when they flock together, look out! Two opposing clans of dragons seek to devastate the inhabitants of each others' territories.
Dragonflock was originally designed for two full monochrome stashes of five trios each (two medium pyramids from each stash will be unused), to be played on a Volcano board.
Those with a lean pyramid supply can still play with three similar five-color Treehouse sets: Use green and blue against red and yellow (or cyan and purple against orange and clear), with no distinction between paired colors.
More attractively, for those wealthy in pyramids: Use white, black, and/or clear pyramid stashes for the larges, another two colors for the mediums, and two further translucent colors for the smalls.
The two dragons that start in the center of the board are trapped there, and neither can move until a third dragon intervenes to resolve the dispute. It is their dispute that has touched off the long-slumbering animosity between the two clans.
