The 2 million castle is in a horrible place. The closest spirit stone has you walking through a maze and opening locked doors. The best houses are the ones next to spirit stones and merchants. 

Castle should have its own merchants and spirit stone, seriously.

there will be a spirit stone over towards oakpass region relatively soon.

Will there be a better way to travel to ones  home? :o I think it looks quite empty without a spirit stone and a few NPC's !
