Since Wilson left and he was my first contact... Can any of you sugest how I proceed now? Do I just void the entire encounter and start over or do I finish this up by myself?

I'd say just void it unless you want to write the whole war on your own. Or alternatively you could continue as if it happened and was just never written. For example, while Dullahan is currently in a bit of a stasis, it currently houses a large number of fairies from before Queen Raidne dropped out. I'm not going to do anything with them, but I'm going to act as if they were still there and just not explained what happened with them. But whatever you want is fine. It doesn't really impact anyone but you and Wilson, so since he left, it's your call.
