Built on one of the two Mantis owned artificial islands, the esteemed House of Storms resembles more a seaside resort than diplomatic office, and the Yoritomo responsible for the Mantis diplomatic mission on World of Dreams would not have it any other way. Traders and dignitaries staying at the embassy can enjoy luxurious single person rooms furnished with large futons, low tables and enough cushions to host a small party. Each room has a sizable bar cabinet stocked with Mantis produced sake and umeshu, a small electronic heater and ice machine ensuring that drinks can be enjoyed both warmed and chilled. Thanks to the locations, nearly all of the rooms offer a seaside view allowing samurai staying at the House of Storms to enjoy a sea breeze simply by opening a window.

While the luxurious suites provided for the Mantis samurai are sizable enough to host guests, the embassy also has a large lounge built on the topmost floor of the building. The lounge sports a large, well-stocked bar cabinet, whose contents are freely available to those staying at the embassy. Large cushions embroidered with various sea monsters surround low and sturdy tables carved from actual wood. A good half of this floor remains uncovered, the exposed space having been turned into a sun-bathing area with an oval jacuzzi large enough to fit two dozen people. Loudhailers and spotlights have been installed in every nook and corner of the lounge, making it easy for the staff to turn the space into a makeshift nightclub, enabling Mantis courtiers to enact a softer sort of diplomacy.

Location special rules: Mantis maintain close ties with many of the smuggling cartels and rogue trade patrons that call World of Dreams their home, well aware that the Scorpion are at least somewhat conscious of their dealings. Yet the Clan of Secrets allow Mantis to benefit from the lax regulations and taxes, knowing that the koku Mantis bring to the city end up fueling the Scorpion economy one way or another. Once per day, a Mantis character may spend a time slot at the embassy contacting the clan's informants. If they do so, they gain a Free Raise on any one Lore: Underworld or Commerce roll the following day (the skill to which the Free Raise is applied must be decided on the day the character spends the time slot at the embassy).
