The gargoyle takes its destoning action. Triggers forges reaction afterwords. (so that is its sad flury and Forges brash strike). Then it surges out another massive action (AP). In this one action, it makes 4 attacks and flies without drawing an AO. It hits and slides Forge, misses Sim, hits and flips Buckthorn, and lands on the Pedestal on the wall opposite of Forge.
Then, Forge fumbles with something. He can still try to move on his turn. If attacked this round, he will shield block.
The warlord is in a position to try something. You can all go (though again Forge can just try to move).
