Council of Elrond

Hi all, another quick Q -- is there any rule that prevents a Fallen Wizard from playing a hero/minion resource at a FW Haven? For example, can I play a Palantir of Orthanc at the FW/haven version of Isengard? Or the various troll factions at a Hidden Haven Ettenmoors?
Can't seem to find anything that would prohibit this, but my bro seems to remember reading something about it somewhere. If anything, this line from insert seems to imply that it would be OK:

For these purposes [of playing resouces], a Fallen-wizard site card (or any Wizardhaven) is both a hero and minion site.

TY!

If it comes to playing a resources at s site, you are right.
A playing resources on site is a different thing. Even if minion Ettenmoors is converted to Wizarhaven by Hidden Haven, it is still minion site card and cannot be targeted by hero resources, e.g. by Hall of Fire.

Ahhh that might be what my bro was thinking of. Thanks as always KK!
