Please help Main Quest Campaign

[aidamei_here]

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!!
