Carn Dum and "Any attack against a minion company at this site is canceled."

[Gamling the Old]

If I play a cave drake on 2 wilderness in the site path, does it get canceled or since we are not attacking at the haven will still continue as normal.

[Konrad Klar]

"If I play a cave drake on 2 wilderness in the site path (...)"
assumes that a target company is moving. "Any attack against a minion company at this site is canceled." does not apply to it.
