The Gate

The gate is a double door gate. It links the real world (Earth) and the fake world (Asteris) together. It is featured in some of the episodes and is in the movie, Conqueror of Shambala. There are many different forms of the gate. In the movie it takes the form of a portal and the regular gate. It opens when a homunculus is transmuted. This happens in the Conqueror of Shambala, when Alphonse Elric transmutes Wrath to make a permanent portal or gate. On the other side, the portal is opened when Van Hohenheim is transmuted to make the portal.
