Hy again, I don't find this anywhere, so here we go:

Sargon:
ILLUSIONARY SWAP: Sargon the Sorcerer can use Smoke Cloud. When he does, he may exchange any two non-immobile objects in the game with each other, as long as one of the objects occupies or is being carried by a characters who occupies the same square as one of the hindering terrain markers he placed. If a chosen object was carried, the replaced object is carried.

And this is the Scorpio' Zodiac Key (not the LE):
ZODIAC KEY (IMMOBILE OBJECT): This object can't be destroyed. Once per game per character, give a character occupying Zodiac key square a power action and roll a d6 that can't be rerolled. On a result of 6, place this object on that character's character card. Modify that character's combat balues +1 and that character can use Probability Control if it cannot already. When that character is defeated, place this object on the square that character last occupied. This object does not count towards your force.

So, can Sargon swap the Zodiac key and bring it close to Scorpio?

Thanks again, I appreciate the help.

No, the Scorpio key is immobile.

Edit: Players Guide Entry.
Either way it would not be able to.

The answer is in the texts themselves.

Sorry guys, I swear I miss the part about "non-immobile" on Sargon' power.

Sorry for bring this useless topic.

Anyway, thanks MisterId and Quebbster.
