When CvCC is considered as combat at Ruins & Lairs? If both deffender and attacker are at Ruins & Lairs, or if at least one company is at Ruins & Lairs, or if at least one company, that under effect of Drughu, is at Ruins & Lairs?

It's a resource effect that affects your own characters and lasts until the end of the turn. I would say that the resource player's site version is the one used. Company vs Company Combat has to be combat, plain and simple. If the relevant company is at a Ruins & Lairs, Drughu will apply, IMO.

I agree with Ben. Since it is a resource it would use the resource player's site as the condition.
