Blackbeak Bluff if it's a big enough stone, you can kill way more than two birds

Naturally, the stranger isn’t very fun and doesn’t appease him with three wishes. Eyes roll in his head and his smile doesn’t quite fade. He thinks of Artaax shoving him to the ground and Blixen at his heels, though he never feared for his life. Artaax may be a killer, but to kill someone once a pack mate? He didn’t have it in him. Neither did Blixen. Here, however, he finds enjoyment in toeing along her annoyance. It’s unprompted and toward, given they’re standing on neutral ground far enough away from another pack that he’s definitely not trespassing, and he would prefer to feel her teeth than not.

Finding that he doesn’t have much of a response, Sirio stands there, watching the stranger over the next three seconds.
