Please help Main Quest Campaign
 

Please help me.
I am doing the main campaign quest. I have three main quests related to each other.

They are:
1.Stop Guilford
2.Find Allies
3.An Alliance with the Elves

I can't fight Guilford (obviously)
I have searched every Island including Medasser and I cannot locate any elves to do an alliance with.
I have searched every map and I cannot locate the Commander of the Elven Army nor can I locate the Castle of Iron Richard on any map.

Thank you so much for your help!!

Someone will probalby provide better information but for the one time I reached that point in the game I believe the aliance with the elves became possible after battling the rezo tower and then talking to rezo more.

well,I cannot do that
 

Well, he does not have anymore dialogue options (excepting his store,should I wish to buy something from him)

The brother and his forces are standing at the front of the castle.

There is no option to battle them

I cannot locate a "Castle of Iron Richard" anywhere..

I cannot locate any other Elves that wish to make an alliance

I'm wondering is this a glitch in the game perhaps?

You know I read that thread but I simply cannot understand

It spoke about alliance with dwarves

I don't have any marks within my quest log about alliance with dwarves

I'm trying to put the pieces of the thread together such that I can figure out what my next move should be but I'm not having success

The castle of Iron Richard (which he occupies before the first Guilford fight) is in Arlania. It is labeled 'Karradun' on the map. The elf you need to talk to is there. He'll send you to the dwarves. The entrance to the underground is also in Arlania, near the jewelry workshop. A line of elves block the way. Talk to the middle one and he'll let you in.
