Enough about the trade center. Where is Hyrule Castle?
Go north of onnet west of snow town and south of wherever you are and you will find yourself on a mountain, go south of the mountain south of the village go west of the village to the market and go north to the castle
Good luck
Features that are currently locked to identified accounts are the primary reason why this should never be done on Classic ie. pyrat quest, holidays events like Halloween, Christmas, etc. I was open to the idea [of something like this] while I was an active member of staff, we even have a large part of it scripted, but I have completely changed my mind. There is potential for negative effects on the community, a good example of this is how bastardized Christmas has become, and Classic has done fine in its 5 years without it.
There is no laziness or 'unwillingness to start' the project, there are just other things that should and will be explored.
