During the Web Era, the Grand Concourse was an expansive shopping, restaurant and bar mall that spanned a hundred kilometers like "an infinite main street". It was not physically located in any single world - instead, it consisted of many different segments on multiple worlds that were connected via military-sized, 200-meter high farcasters. It was similar in concept to the River Tethys or to Martin Silenus multi-world house.
The following worlds as known to have strips in the Grand Concourse:
- Tsingtao-Hsishuang Panna (half-kilometer long section connecting to New Earth) 
- New Earth
- Nevermore (short section consisting of a seaside strip)
THP was part of the Grand Concourse, which had a half-kilometer section in Tsingtao that connected to New Earth, as well as to the section on Nevermore that consisted of a short seaside strip. It was also part of the River Tethys.
