And how I get the Enclave? The Elven lady get out of the lighthouse and I can't get in to enclave?
The elven lady I mentioned to Xiakankan is different from the one in the lighthouse. The one in the lighthouse is connected to Nel's questline. The elf that grants you access to the enclave is introduced in the main questline.
Just continue the main questline (leveling up and going to the guild hall for assignments) and you'll eventually meet the enclave elf. She's blonde.
