Isengard

[Muzgash]

A couple of related questions that I'm still no 100% on after scouring the forums.

1) If I have a company at FW Isengard, can one of my other companies not at FW Isengard move to Hero/Minion Isengard?

2) If I have a company at FW Isengard, can one of my other companies at FW Isengard either move to Hero/Minion Isengard or somehow replace their current FW Isengard site with the hero/minion version?

3) If it is possible to simultaneously have a company at FW Isengard and another at Hero/Minion Isengard, can you merge those two companies?

4) If you have a Hero/Minion Isengard in your discard pile, can you still move to FW Isengard?

Thanks,
Muzgash

If any version of a site is in play or in your discard pile, you may not play another
version of that site.

This explicitly forbids (4) and implicitly prevents (1), (3) from happening*.
If it comes to (2), moving from FW Isengard to other version is per impicite* forbidden by quoted CRF rule; rules do not provide an option of voluntary replacing FW site with other version, but such replacing may be forced by some hazards or resources.

*) Second copy (and possibly other version) of Isengard may appear in play in result of Chance of Being Lost (for example) and this would not violate quoted CRF rule.
I may be wrong on this but I do not know a rule that would forbid a moving from site A to site A using region movement.

Thank you, I knew I was missing something simple. If I'm understanding correctly, it would be possible for a lone company at FW Isengard to move to Hero/Minion Isengard as long as everyone came along. In such a case, would it be possible for another company to meet them at their destination (Hero/Minion Isengard) as long as you revealed the new site for the company currently at FW Isengard first? So company A is moves from FW Isengard to Minion Isengard, then company B moves from anywhere else to Minion Isengard.

If you have second version of Isengard (as result of Chance of Being Lost played by opponent), then both version may be new sites.
If it comes to joining companies at site:

Companies at the same non-Haven/non-Darkhaven site must join at the end of all
movement/hazard phases, before the site phase starts. Companies at the same Haven/Darkhaven site may join at this time.

at the end of all M/H phases some companies may have as its new site hero/minion Isengard site card, some other FW Isengard site card.

Both companies would be at the same site but first would not be at the same non-haven site as second (that would be at haven site).
For this reason I think that they cannot/do not must join.
At least by letter of rules (not sure about spirit).
