Manifestations of unique characters

[Balin]

We all know when an avatar comes into play, any manifestation of him is discarded (i.e. Radagast as a wizard discards Radagast the Tamer). What happens if you try to play Galadriel as a character when Lady of the Golden Wood is already in play?

I can't find a clear rule about this.

Thanks in advance.

[Bandobras Took]

Hazard Manifestations of Radagast, etc. contain a statement on the cards that they are discarded if their character manifestation comes into play.

If a Manifestation lacks this phrase, then you may not play a different manifestation.

With of course the exception of dragons.

Have a look at the DM rules book:

Certain entities (e.g., the Balrog, Gollum, Lobelia, etc.) have several different manifestations, each represented by a different MECCG card.

* If one manifestation of such an entity is already in play, you may not play another manifestation of the same entity.
* If an attack from a manifestation is defeated, the manifestation is removed from play and you may not play any further manifestations of the same entity.

Exception: Different manifestations of the same unique Dragon may be in play at the same time.

Note: If one card says that it is the manifestation of another card, these restrictions apply to both cards.
