Council of Elrond

Yet another newbish question, this time about Cave Drake:

Dragon. Two strikes. Attacker chooses defending characters. Two Wildernesses in site path are required.

1. Can it be played on any R&L, or only on those with two [W] in the site path?
2. Can it be played when there are two [W] in the company's site path, but not in site's site path, e.g. on a company moving through two [W] regions, but to a site without two [W] in the site path?

Thanks!

A Cave-drake may be played on a company if

1. they are at or move to a (no matter what the site's site path is)
2. they move through at least (company's site path is meant here; need not be directly consecutive)

I would add:
Compare it with Rain-Drake and Giant Spiders, and Nameless Thing.
If there are any region, or site symbols then the site or path does not need to met other conditions.
Text of creature card may specify additional keying possibilities, or is redundant to the symbols (that is source of confusion, like any redundancy in this game), or both.
