I have been trying to get back to this portal but am not able to. When i do a lookup for it it does not find it, When i enter the cords, it gives me a Empty Village(o,o) and locks up...
Mystic Portals are a one-way trip - you cannot go back to them once you've passed through it. You can lead more armies through it to the destination, but none can return through that portal.
Your options are to:
-- Find the natural portal (each continent has two - one by the northern and southern most corners of the continent bordering the next continent) of the continent you're on that's closest to your city and attempt to walk home.
-- Kill your troops in some wilds in that continent to spare yourself the walk.
-- Port a city to collect your troops.
-- (best option) Suicide your troops in an instance and revive them where you want them.
